+Linux IOMMU Support
+===================
+
+The architecture spec can be obtained from the below location.
+
+http://www.intel.com/technology/virtualization/
+
+This guide gives a quick cheat sheet for some basic understanding.
+
+Some Keywords
+
+DMAR - DMA remapping
+DRHD - DMA Engine Reporting Structure
+RMRR - Reserved memory Region Reporting Structure
+ZLR  - Zero length reads from PCI devices
+IOVA - IO Virtual address.
+
+Basic stuff
+-----------
+
+ACPI enumerates and lists the different DMA engines in the platform, and
+device scope relationships between PCI devices and which DMA engine  controls
+them.
+
+What is RMRR?
+-------------
+
+There are some devices the BIOS controls, for e.g USB devices to perform
+PS2 emulation. The regions of memory used for these devices are marked
+reserved in the e820 map. When we turn on DMA translation, DMA to those
+regions will fail. Hence BIOS uses RMRR to specify these regions along with
+devices that need to access these regions. OS is expected to setup
+unity mappings for these regions for these devices to access these regions.
+
+How is IOVA generated?
+---------------------
+
+Well behaved drivers call pci_map_*() calls before sending command to device
+that needs to perform DMA. Once DMA is completed and mapping is no longer
+required, device performs a pci_unmap_*() calls to unmap the region.
+
+The Intel IOMMU driver allocates a virtual address per domain. Each PCIE
+device has its own domain (hence protection). Devices under p2p bridges
+share the virtual address with all devices under the p2p bridge due to
+transaction id aliasing for p2p bridges.
+
+IOVA generation is pretty generic. We used the same technique as vmalloc()
+but these are not global address spaces, but separate for each domain.
+Different DMA engines may support different number of domains.
+
+We also allocate gaurd pages with each mapping, so we can attempt to catch
+any overflow that might happen.
+
+
+Graphics Problems?
+------------------
+If you encounter issues with graphics devices, you can try adding
+option intel_iommu=igfx_off to turn off the integrated graphics engine.
+
+If it happens to be a PCI device included in the INCLUDE_ALL Engine,
+then try enabling CONFIG_DMAR_GFX_WA to setup a 1-1 map. We hear
+graphics drivers may be in process of using DMA api's in the near
+future and at that time this option can be yanked out.
+
+Some exceptions to IOVA
+-----------------------
+Interrupt ranges are not address translated, (0xfee00000 - 0xfeefffff).
+The same is true for peer to peer transactions. Hence we reserve the
+address from PCI MMIO ranges so they are not allocated for IOVA addresses.
+
+
+Fault reporting
+---------------
+When errors are reported, the DMA engine signals via an interrupt. The fault
+reason and device that caused it with fault reason is printed on console.
+
+See below for sample.
+
+
+Boot Message Sample
+-------------------
+
+Something like this gets printed indicating presence of DMAR tables
+in ACPI.
+
+ACPI: DMAR (v001 A M I  OEMDMAR  0x00000001 MSFT 0x00000097) @ 0x000000007f5b5ef0
+
+When DMAR is being processed and initialized by ACPI, prints DMAR locations
+and any RMRR's processed.
+

+ACPI DMAR:RMRR base: 0x000000007f600000 end: 0x000000007fffffff

+1. Control Groups
+==========
+
+1.1 What are cgroups ?
+----------------------
+
+Control Groups provide a mechanism for aggregating/partitioning sets of
+tasks, and all their future children, into hierarchical groups with
+specialized behaviour.
+
+Definitions:
+
+A *cgroup* associates a set of tasks with a set of parameters for one
+or more subsystems.
+
+A *subsystem* is a module that makes use of the task grouping
+facilities provided by cgroups to treat groups of tasks in
+particular ways. A subsystem is typically a "resource controller" that
+schedules a resource or applies per-cgroup limits, but it may be
+anything that wants to act on a group of processes, e.g. a
+virtualization subsystem.
+
+A *hierarchy* is a set of cgroups arranged in a tree, such that
+every task in the system is in exactly one of the cgroups in the
+hierarchy, and a set of subsystems; each subsystem has system-specific
+state attached to each cgroup in the hierarchy.  Each hierarchy has
+an instance of the cgroup virtual filesystem associated with it.
+
+At any one time there may be multiple active hierachies of task
+cgroups. Each hierarchy is a partition of all tasks in the system.
+
+User level code may create and destroy cgroups by name in an
+instance of the cgroup virtual file system, specify and query to
+which cgroup a task is assigned, and list the task pids assigned to
+a cgroup. Those creations and assignments only affect the hierarchy
+associated with that instance of the cgroup file system.
+
+On their own, the only use for cgroups is for simple job
+tracking. The intention is that other subsystems hook into the generic
+cgroup support to provide new attributes for cgroups, such as
+accounting/limiting the resources which processes in a cgroup can
+access. For example, cpusets (see Documentation/cpusets.txt) allows
+you to associate a set of CPUs and a set of memory nodes with the
+tasks in each cgroup.
+
+1.2 Why are cgroups needed ?
+----------------------------
+
+There are multiple efforts to provide process aggregations in the
+Linux kernel, mainly for resource tracking purposes. Such efforts
+include cpusets, CKRM/ResGroups, UserBeanCounters, and virtual server
+namespaces. These all require the basic notion of a
+grouping/partitioning of processes, with newly forked processes ending
+in the same group (cgroup) as their parent process.
+
+The kernel cgroup patch provides the minimum essential kernel
+mechanisms required to efficiently implement such groups. It has
+minimal impact on the system fast paths, and provides hooks for
+specific subsystems such as cpusets to provide additional behaviour as
+desired.
+
+Multiple hierarchy support is provided to allow for situations where
+the division of tasks into cgroups is distinctly different for
+different subsystems - having parallel hierarchies allows each
+hierarchy to be a natural division of tasks, without having to handle
+complex combinations of tasks that would be present if several
+unrelated subsystems needed to be forced into the same tree of
+cgroups.
+
+At one extreme, each resource controller or subsystem could be in a
+separate hierarchy; at the other extreme, all subsystems
+would be attached to the same hierarchy.
+
+As an example of a scenario (originally proposed by vatsa@in.ibm.com)
+that can benefit from multiple hierarchies, consider a large
+university server with various users - students, professors, system
+tasks etc. The resource planning for this server could be along the
+following lines:
+
+       CPU :           Top cpuset
+                       /       \
+               CPUSet1         CPUSet2
+                  |              |
+               (Profs)         (Students)
+
+               In addition (system tasks) are attached to topcpuset (so
+               that they can run anywhere) with a limit of 20%
+
+       Memory : Professors (50%), students (30%), system (20%)
+
+       Disk : Prof (50%), students (30%), system (20%)
+
+       Network : WWW browsing (20%), Network File System (60%), others (20%)
+                               / \
+                       Prof (15%) students (5%)
+
+Browsers like firefox/lynx go into the WWW network class, while (k)nfsd go
+into NFS network class.
+
+At the same time firefox/lynx will share an appropriate CPU/Memory class
+depending on who launched it (prof/student).
+
+With the ability to classify tasks differently for different resources
+(by putting those resource subsystems in different hierarchies) then
+the admin can easily set up a script which receives exec notifications
+and depending on who is launching the browser he can
+
+       # echo browser_pid > /mnt/<restype>/<userclass>/tasks
+
+With only a single hierarchy, he now would potentially have to create
+a separate cgroup for every browser launched and associate it with
+approp network and other resource class.  This may lead to
+proliferation of such cgroups.
+
+Also lets say that the administrator would like to give enhanced network
+access temporarily to a student's browser (since it is night and the user
+wants to do online gaming :)  OR give one of the students simulation
+apps enhanced CPU power,
+
+With ability to write pids directly to resource classes, its just a
+matter of :
+
+       # echo pid > /mnt/network/<new_class>/tasks
+       (after some time)
+       # echo pid > /mnt/network/<orig_class>/tasks
+
+Without this ability, he would have to split the cgroup into
+multiple separate ones and then associate the new cgroups with the
+new resource classes.
+
+
+
+1.3 How are cgroups implemented ?
+---------------------------------
+
+Control Groups extends the kernel as follows:
+
+ - Each task in the system has a reference-counted pointer to a
+   css_set.
+
+ - A css_set contains a set of reference-counted pointers to
+   cgroup_subsys_state objects, one for each cgroup subsystem
+   registered in the system. There is no direct link from a task to
+   the cgroup of which it's a member in each hierarchy, but this
+   can be determined by following pointers through the
+   cgroup_subsys_state objects. This is because accessing the
+   subsystem state is something that's expected to happen frequently
+   and in performance-critical code, whereas operations that require a
+   task's actual cgroup assignments (in particular, moving between
+   cgroups) are less common. A linked list runs through the cg_list
+   field of each task_struct using the css_set, anchored at
+   css_set->tasks.
+
+ - A cgroup hierarchy filesystem can be mounted  for browsing and
+   manipulation from user space.
+
+ - You can list all the tasks (by pid) attached to any cgroup.
+
+The implementation of cgroups requires a few, simple hooks
+into the rest of the kernel, none in performance critical paths:
+
+ - in init/main.c, to initialize the root cgroups and initial
+   css_set at system boot.
+
+ - in fork and exit, to attach and detach a task from its css_set.
+
+In addition a new file system, of type "cgroup" may be mounted, to
+enable browsing and modifying the cgroups presently known to the
+kernel.  When mounting a cgroup hierarchy, you may specify a
+comma-separated list of subsystems to mount as the filesystem mount
+options.  By default, mounting the cgroup filesystem attempts to
+mount a hierarchy containing all registered subsystems.
+
+If an active hierarchy with exactly the same set of subsystems already
+exists, it will be reused for the new mount. If no existing hierarchy
+matches, and any of the requested subsystems are in use in an existing
+hierarchy, the mount will fail with -EBUSY. Otherwise, a new hierarchy
+is activated, associated with the requested subsystems.
+
+It's not currently possible to bind a new subsystem to an active
+cgroup hierarchy, or to unbind a subsystem from an active cgroup
+hierarchy. This may be possible in future, but is fraught with nasty
+error-recovery issues.
+
+When a cgroup filesystem is unmounted, if there are any
+child cgroups created below the top-level cgroup, that hierarchy
+will remain active even though unmounted; if there are no
+child cgroups then the hierarchy will be deactivated.
+
+No new system calls are added for cgroups - all support for
+querying and modifying cgroups is via this cgroup file system.
+
+Each task under /proc has an added file named 'cgroup' displaying,
+for each active hierarchy, the subsystem names and the cgroup name
+as the path relative to the root of the cgroup file system.
+
+Each cgroup is represented by a directory in the cgroup file system
+containing the following files describing that cgroup:
+
+ - tasks: list of tasks (by pid) attached to that cgroup
+ - notify_on_release flag: run /sbin/cgroup_release_agent on exit?
+
+Other subsystems such as cpusets may add additional files in each
+cgroup dir
+
+New cgroups are created using the mkdir system call or shell
+command.  The properties of a cgroup, such as its flags, are
+modified by writing to the appropriate file in that cgroups
+directory, as listed above.
+
+The named hierarchical structure of nested cgroups allows partitioning
+a large system into nested, dynamically changeable, "soft-partitions".
+
+The attachment of each task, automatically inherited at fork by any
+children of that task, to a cgroup allows organizing the work load
+on a system into related sets of tasks.  A task may be re-attached to
+any other cgroup, if allowed by the permissions on the necessary
+cgroup file system directories.
+
+When a task is moved from one cgroup to another, it gets a new
+css_set pointer - if there's an already existing css_set with the
+desired collection of cgroups then that group is reused, else a new
+css_set is allocated. Note that the current implementation uses a
+linear search to locate an appropriate existing css_set, so isn't
+very efficient. A future version will use a hash table for better
+performance.
+
+To allow access from a cgroup to the css_sets (and hence tasks)
+that comprise it, a set of cg_cgroup_link objects form a lattice;
+each cg_cgroup_link is linked into a list of cg_cgroup_links for
+a single cgroup on its cont_link_list field, and a list of
+cg_cgroup_links for a single css_set on its cg_link_list.
+
+Thus the set of tasks in a cgroup can be listed by iterating over
+each css_set that references the cgroup, and sub-iterating over
+each css_set's task set.
+
+The use of a Linux virtual file system (vfs) to represent the
+cgroup hierarchy provides for a familiar permission and name space
+for cgroups, with a minimum of additional kernel code.
+
+1.4 What does notify_on_release do ?
+------------------------------------
+
+*** notify_on_release is disabled in the current patch set. It will be
+*** reactivated in a future patch in a less-intrusive manner
+
+If the notify_on_release flag is enabled (1) in a cgroup, then
+whenever the last task in the cgroup leaves (exits or attaches to
+some other cgroup) and the last child cgroup of that cgroup
+is removed, then the kernel runs the command specified by the contents
+of the "release_agent" file in that hierarchy's root directory,
+supplying the pathname (relative to the mount point of the cgroup
+file system) of the abandoned cgroup.  This enables automatic
+removal of abandoned cgroups.  The default value of
+notify_on_release in the root cgroup at system boot is disabled
+(0).  The default value of other cgroups at creation is the current
+value of their parents notify_on_release setting. The default value of
+a cgroup hierarchy's release_agent path is empty.
+
+1.5 How do I use cgroups ?
+--------------------------
+
+To start a new job that is to be contained within a cgroup, using
+the "cpuset" cgroup subsystem, the steps are something like:
+
+ 1) mkdir /dev/cgroup
+ 2) mount -t cgroup -ocpuset cpuset /dev/cgroup
+ 3) Create the new cgroup by doing mkdir's and write's (or echo's) in
+    the /dev/cgroup virtual file system.
+ 4) Start a task that will be the "founding father" of the new job.
+ 5) Attach that task to the new cgroup by writing its pid to the
+    /dev/cgroup tasks file for that cgroup.
+ 6) fork, exec or clone the job tasks from this founding father task.
+
+For example, the following sequence of commands will setup a cgroup
+named "Charlie", containing just CPUs 2 and 3, and Memory Node 1,
+and then start a subshell 'sh' in that cgroup:
+
+  mount -t cgroup cpuset -ocpuset /dev/cgroup
+  cd /dev/cgroup
+  mkdir Charlie
+  cd Charlie
+  /bin/echo 2-3 > cpus
+  /bin/echo 1 > mems
+  /bin/echo $$ > tasks
+  sh
+  # The subshell 'sh' is now running in cgroup Charlie
+  # The next line should display '/Charlie'
+  cat /proc/self/cgroup
+
+2. Usage Examples and Syntax
+============================
+
+2.1 Basic Usage
+---------------
+
+Creating, modifying, using the cgroups can be done through the cgroup
+virtual filesystem.
+
+To mount a cgroup hierarchy will all available subsystems, type:
+# mount -t cgroup xxx /dev/cgroup
+
+The "xxx" is not interpreted by the cgroup code, but will appear in
+/proc/mounts so may be any useful identifying string that you like.
+
+To mount a cgroup hierarchy with just the cpuset and numtasks
+subsystems, type:
+# mount -t cgroup -o cpuset,numtasks hier1 /dev/cgroup
+
+To change the set of subsystems bound to a mounted hierarchy, just
+remount with different options:
+
+# mount -o remount,cpuset,ns  /dev/cgroup
+
+Note that changing the set of subsystems is currently only supported
+when the hierarchy consists of a single (root) cgroup. Supporting
+the ability to arbitrarily bind/unbind subsystems from an existing
+cgroup hierarchy is intended to be implemented in the future.
+
+Then under /dev/cgroup you can find a tree that corresponds to the
+tree of the cgroups in the system. For instance, /dev/cgroup
+is the cgroup that holds the whole system.
+
+If you want to create a new cgroup under /dev/cgroup:
+# cd /dev/cgroup
+# mkdir my_cgroup
+
+Now you want to do something with this cgroup.
+# cd my_cgroup
+
+In this directory you can find several files:
+# ls
+notify_on_release release_agent tasks
+(plus whatever files are added by the attached subsystems)
+
+Now attach your shell to this cgroup:
+# /bin/echo $$ > tasks
+
+You can also create cgroups inside your cgroup by using mkdir in this
+directory.
+# mkdir my_sub_cs
+
+To remove a cgroup, just use rmdir:
+# rmdir my_sub_cs
+
+This will fail if the cgroup is in use (has cgroups inside, or
+has processes attached, or is held alive by other subsystem-specific
+reference).
+
+2.2 Attaching processes
+-----------------------
+
+# /bin/echo PID > tasks
+
+Note that it is PID, not PIDs. You can only attach ONE task at a time.
+If you have several tasks to attach, you have to do it one after another:
+
+# /bin/echo PID1 > tasks
+# /bin/echo PID2 > tasks
+	...
+# /bin/echo PIDn > tasks
+
+3. Kernel API
+=============
+
+3.1 Overview
+------------
+
+Each kernel subsystem that wants to hook into the generic cgroup
+system needs to create a cgroup_subsys object. This contains
+various methods, which are callbacks from the cgroup system, along
+with a subsystem id which will be assigned by the cgroup system.
+
+Other fields in the cgroup_subsys object include:
+
+- subsys_id: a unique array index for the subsystem, indicating which
+  entry in cgroup->subsys[] this subsystem should be
+  managing. Initialized by cgroup_register_subsys(); prior to this
+  it should be initialized to -1
+
+- hierarchy: an index indicating which hierarchy, if any, this
+  subsystem is currently attached to. If this is -1, then the
+  subsystem is not attached to any hierarchy, and all tasks should be
+  considered to be members of the subsystem's top_cgroup. It should
+  be initialized to -1.
+
+- name: should be initialized to a unique subsystem name prior to
+  calling cgroup_register_subsystem. Should be no longer than
+  MAX_CGROUP_TYPE_NAMELEN
+
+Each cgroup object created by the system has an array of pointers,
+indexed by subsystem id; this pointer is entirely managed by the
+subsystem; the generic cgroup code will never touch this pointer.
+
+3.2 Synchronization
+-------------------
+
+There is a global mutex, cgroup_mutex, used by the cgroup
+system. This should be taken by anything that wants to modify a
+cgroup. It may also be taken to prevent cgroups from being
+modified, but more specific locks may be more appropriate in that
+situation.
+
+See kernel/cgroup.c for more details.
+
+Subsystems can take/release the cgroup_mutex via the functions
+cgroup_lock()/cgroup_unlock(), and can
+take/release the callback_mutex via the functions
+cgroup_lock()/cgroup_unlock().
+
+Accessing a task's cgroup pointer may be done in the following ways:
+- while holding cgroup_mutex
+- while holding the task's alloc_lock (via task_lock())
+- inside an rcu_read_lock() section via rcu_dereference()
+
+3.3 Subsystem API
+--------------------------
+
+Each subsystem should:
+
+- add an entry in linux/cgroup_subsys.h
+- define a cgroup_subsys object called <name>_subsys
+
+Each subsystem may export the following methods. The only mandatory
+methods are create/destroy. Any others that are null are presumed to
+be successful no-ops.
+
+struct cgroup_subsys_state *create(struct cgroup *cont)
+LL=cgroup_mutex
+
+Called to create a subsystem state object for a cgroup. The
+subsystem should allocate its subsystem state object for the passed
+cgroup, returning a pointer to the new object on success or a
+negative error code. On success, the subsystem pointer should point to
+a structure of type cgroup_subsys_state (typically embedded in a
+larger subsystem-specific object), which will be initialized by the
+cgroup system. Note that this will be called at initialization to
+create the root subsystem state for this subsystem; this case can be
+identified by the passed cgroup object having a NULL parent (since
+it's the root of the hierarchy) and may be an appropriate place for
+initialization code.
+
+void destroy(struct cgroup *cont)
+LL=cgroup_mutex
+
+The cgroup system is about to destroy the passed cgroup; the
+subsystem should do any necessary cleanup
+
+int can_attach(struct cgroup_subsys *ss, struct cgroup *cont,
+	       struct task_struct *task)
+LL=cgroup_mutex
+
+Called prior to moving a task into a cgroup; if the subsystem
+returns an error, this will abort the attach operation.  If a NULL
+task is passed, then a successful result indicates that *any*
+unspecified task can be moved into the cgroup. Note that this isn't
+called on a fork. If this method returns 0 (success) then this should
+remain valid while the caller holds cgroup_mutex.
+
+void attach(struct cgroup_subsys *ss, struct cgroup *cont,
+	    struct cgroup *old_cont, struct task_struct *task)
+LL=cgroup_mutex
+
+
+Called after the task has been attached to the cgroup, to allow any
+post-attachment activity that requires memory allocations or blocking.
+
+void fork(struct cgroup_subsy *ss, struct task_struct *task)
+LL=callback_mutex, maybe read_lock(tasklist_lock)
+
+Called when a task is forked into a cgroup. Also called during
+registration for all existing tasks.
+
+void exit(struct cgroup_subsys *ss, struct task_struct *task)
+LL=callback_mutex
+
+Called during task exit
+
+int populate(struct cgroup_subsys *ss, struct cgroup *cont)
+LL=none
+
+Called after creation of a cgroup to allow a subsystem to populate
+the cgroup directory with file entries.  The subsystem should make
+calls to cgroup_add_file() with objects of type cftype (see
+include/linux/cgroup.h for details).  Note that although this
+method can return an error code, the error code is currently not
+always handled well.
+
+void post_clone(struct cgroup_subsys *ss, struct cgroup *cont)
+
+Called at the end of cgroup_clone() to do any paramater
+initialization which might be required before a task could attach.  For
+example in cpusets, no task may attach before 'cpus' and 'mems' are set
+up.
+
+void bind(struct cgroup_subsys *ss, struct cgroup *root)
+LL=callback_mutex
+
+Called when a cgroup subsystem is rebound to a different hierarchy
+and root cgroup. Currently this will only involve movement between
+the default hierarchy (which never has sub-cgroups) and a hierarchy
+that is being created/destroyed (and hence has no sub-cgroups).
+
+4. Questions
+============
+
+Q: what's up with this '/bin/echo' ?
+A: bash's builtin 'echo' command does not check calls to write() against
+   errors. If you use it in the cgroup file system, you won't be
+   able to tell whether a command succeeded or failed.
+
+Q: When I attach processes, only the first of the line gets really attached !
+A: We can only return one error code per call to write(). So you should also
+   put only ONE pid.

+1.7 What is sched_load_balance ?
+--------------------------------
+
+The kernel scheduler (kernel/sched.c) automatically load balances
+tasks.  If one CPU is underutilized, kernel code running on that
+CPU will look for tasks on other more overloaded CPUs and move those
+tasks to itself, within the constraints of such placement mechanisms
+as cpusets and sched_setaffinity.
+
+The algorithmic cost of load balancing and its impact on key shared
+kernel data structures such as the task list increases more than
+linearly with the number of CPUs being balanced.  So the scheduler
+has support to  partition the systems CPUs into a number of sched
+domains such that it only load balances within each sched domain.
+Each sched domain covers some subset of the CPUs in the system;
+no two sched domains overlap; some CPUs might not be in any sched
+domain and hence won't be load balanced.
+
+Put simply, it costs less to balance between two smaller sched domains
+than one big one, but doing so means that overloads in one of the
+two domains won't be load balanced to the other one.
+
+By default, there is one sched domain covering all CPUs, except those
+marked isolated using the kernel boot time "isolcpus=" argument.
+
+This default load balancing across all CPUs is not well suited for
+the following two situations:
+ 1) On large systems, load balancing across many CPUs is expensive.
+    If the system is managed using cpusets to place independent jobs
+    on separate sets of CPUs, full load balancing is unnecessary.
+ 2) Systems supporting realtime on some CPUs need to minimize
+    system overhead on those CPUs, including avoiding task load
+    balancing if that is not needed.
+
+When the per-cpuset flag "sched_load_balance" is enabled (the default
+setting), it requests that all the CPUs in that cpusets allowed 'cpus'
+be contained in a single sched domain, ensuring that load balancing
+can move a task (not otherwised pinned, as by sched_setaffinity)
+from any CPU in that cpuset to any other.
+
+When the per-cpuset flag "sched_load_balance" is disabled, then the
+scheduler will avoid load balancing across the CPUs in that cpuset,
+--except-- in so far as is necessary because some overlapping cpuset
+has "sched_load_balance" enabled.
+
+So, for example, if the top cpuset has the flag "sched_load_balance"
+enabled, then the scheduler will have one sched domain covering all
+CPUs, and the setting of the "sched_load_balance" flag in any other
+cpusets won't matter, as we're already fully load balancing.
+
+Therefore in the above two situations, the top cpuset flag
+"sched_load_balance" should be disabled, and only some of the smaller,
+child cpusets have this flag enabled.
+
+When doing this, you don't usually want to leave any unpinned tasks in
+the top cpuset that might use non-trivial amounts of CPU, as such tasks
+may be artificially constrained to some subset of CPUs, depending on
+the particulars of this flag setting in descendent cpusets.  Even if
+such a task could use spare CPU cycles in some other CPUs, the kernel
+scheduler might not consider the possibility of load balancing that
+task to that underused CPU.
+
+Of course, tasks pinned to a particular CPU can be left in a cpuset
+that disables "sched_load_balance" as those tasks aren't going anywhere
+else anyway.
+
+There is an impedance mismatch here, between cpusets and sched domains.
+Cpusets are hierarchical and nest.  Sched domains are flat; they don't
+overlap and each CPU is in at most one sched domain.
+
+It is necessary for sched domains to be flat because load balancing
+across partially overlapping sets of CPUs would risk unstable dynamics
+that would be beyond our understanding.  So if each of two partially
+overlapping cpusets enables the flag 'sched_load_balance', then we
+form a single sched domain that is a superset of both.  We won't move
+a task to a CPU outside it cpuset, but the scheduler load balancing
+code might waste some compute cycles considering that possibility.
+
+This mismatch is why there is not a simple one-to-one relation
+between which cpusets have the flag "sched_load_balance" enabled,
+and the sched domain configuration.  If a cpuset enables the flag, it
+will get balancing across all its CPUs, but if it disables the flag,
+it will only be assured of no load balancing if no other overlapping
+cpuset enables the flag.
+
+If two cpusets have partially overlapping 'cpus' allowed, and only
+one of them has this flag enabled, then the other may find its
+tasks only partially load balanced, just on the overlapping CPUs.
+This is just the general case of the top_cpuset example given a few
+paragraphs above.  In the general case, as in the top cpuset case,
+don't leave tasks that might use non-trivial amounts of CPU in
+such partially load balanced cpusets, as they may be artificially
+constrained to some subset of the CPUs allowed to them, for lack of
+load balancing to the other CPUs.
+
+1.7.1 sched_load_balance implementation details.
+------------------------------------------------
+
+The per-cpuset flag 'sched_load_balance' defaults to enabled (contrary
+to most cpuset flags.)  When enabled for a cpuset, the kernel will
+ensure that it can load balance across all the CPUs in that cpuset
+(makes sure that all the CPUs in the cpus_allowed of that cpuset are
+in the same sched domain.)
+
+If two overlapping cpusets both have 'sched_load_balance' enabled,
+then they will be (must be) both in the same sched domain.
+
+If, as is the default, the top cpuset has 'sched_load_balance' enabled,
+then by the above that means there is a single sched domain covering
+the whole system, regardless of any other cpuset settings.
+
+The kernel commits to user space that it will avoid load balancing
+where it can.  It will pick as fine a granularity partition of sched
+domains as it can while still providing load balancing for any set
+of CPUs allowed to a cpuset having 'sched_load_balance' enabled.
+
+The internal kernel cpuset to scheduler interface passes from the
+cpuset code to the scheduler code a partition of the load balanced
+CPUs in the system. This partition is a set of subsets (represented
+as an array of cpumask_t) of CPUs, pairwise disjoint, that cover all
+the CPUs that must be load balanced.
+
+Whenever the 'sched_load_balance' flag changes, or CPUs come or go
+from a cpuset with this flag enabled, or a cpuset with this flag
+enabled is removed, the cpuset code builds a new such partition and
+passes it to the scheduler sched domain setup code, to have the sched
+domains rebuilt as necessary.
+
+This partition exactly defines what sched domains the scheduler should
+setup - one sched domain for each element (cpumask_t) in the partition.
+
+The scheduler remembers the currently active sched domain partitions.
+When the scheduler routine partition_sched_domains() is invoked from
+the cpuset code to update these sched domains, it compares the new
+partition requested with the current, and updates its sched domains,
+removing the old and adding the new, for each change.

- * approximately by looking at the addresses in the code.  I chose the common
- * case of reading a memory location into the %eax register:
- *
- *  movl <some-address>, %eax
- *
- * This gets encoded as five bytes: "0xA1 <4-byte-address>".  For example,
- * "0xA1 0x18 0x60 0x47 0xC0" reads the address 0xC0476018 into %eax.
- *
- * In this example can guess that the kernel was compiled with
- * CONFIG_PAGE_OFFSET set to 0xC0000000 (it's always a round number).  If the
- * kernel were larger than 16MB, we might see 0xC1 addresses show up, but our
- * kernel isn't that bloated yet.
- *
- * Unfortunately, x86 has variable-length instructions, so finding this
- * particular instruction properly involves writing a disassembler.  Instead,
- * we rely on statistics.  We look for "0xA1" and tally the different bytes
- * which occur 4 bytes later (the "0xC0" in our example above).  When one of
- * those bytes appears three times, we can be reasonably confident that it
- * forms the start of CONFIG_PAGE_OFFSET.

+ 	             Using the Linux Kernel Markers
+
+			    Mathieu Desnoyers
+
+
+This document introduces Linux Kernel Markers and their use. It provides
+examples of how to insert markers in the kernel and connect probe functions to
+them and provides some examples of probe functions.
+
+
+* Purpose of markers
+
+A marker placed in code provides a hook to call a function (probe) that you can
+provide at runtime. A marker can be "on" (a probe is connected to it) or "off"
+(no probe is attached). When a marker is "off" it has no effect, except for
+adding a tiny time penalty (checking a condition for a branch) and space
+penalty (adding a few bytes for the function call at the end of the
+instrumented function and adds a data structure in a separate section).  When a
+marker is "on", the function you provide is called each time the marker is
+executed, in the execution context of the caller. When the function provided
+ends its execution, it returns to the caller (continuing from the marker site).
+
+You can put markers at important locations in the code. Markers are
+lightweight hooks that can pass an arbitrary number of parameters,
+described in a printk-like format string, to the attached probe function.
+
+They can be used for tracing and performance accounting.
+
+
+* Usage
+
+In order to use the macro trace_mark, you should include linux/marker.h.
+
+#include <linux/marker.h>
+
+And,
+
+trace_mark(subsystem_event, "%d %s", someint, somestring);
+Where :
+- subsystem_event is an identifier unique to your event
+    - subsystem is the name of your subsystem.
+    - event is the name of the event to mark.
+- "%d %s" is the formatted string for the serializer.
+- someint is an integer.
+- somestring is a char pointer.
+
+Connecting a function (probe) to a marker is done by providing a probe (function
+to call) for the specific marker through marker_probe_register() and can be
+activated by calling marker_arm(). Marker deactivation can be done by calling
+marker_disarm() as many times as marker_arm() has been called. Removing a probe
+is done through marker_probe_unregister(); it will disarm the probe and make
+sure there is no caller left using the probe when it returns. Probe removal is
+preempt-safe because preemption is disabled around the probe call. See the
+"Probe example" section below for a sample probe module.
+
+The marker mechanism supports inserting multiple instances of the same marker.
+Markers can be put in inline functions, inlined static functions, and
+unrolled loops as well as regular functions.
+
+The naming scheme "subsystem_event" is suggested here as a convention intended
+to limit collisions. Marker names are global to the kernel: they are considered
+as being the same whether they are in the core kernel image or in modules.
+Conflicting format strings for markers with the same name will cause the markers
+to be detected to have a different format string not to be armed and will output
+a printk warning which identifies the inconsistency:
+
+"Format mismatch for probe probe_name (format), marker (format)"
+
+
+* Probe / marker example
+
+See the example provided in samples/markers/src
+
+Compile them with your kernel.
+
+Run, as root :
+modprobe marker-example (insmod order is not important)
+modprobe probe-example
+cat /proc/marker-example (returns an expected error)
+rmmod marker-example probe-example

+
+MEMORY_GOING_OFFLINE
+  Generated to begin the process of offlining memory. Allocations are no
+  longer possible from the memory but some of the memory to be offlined
+  is still in use. The callback can be used to free memory known to a
+  subsystem from the indicated memory section.
+
+MEMORY_CANCEL_OFFLINE
+  Generated if MEMORY_GOING_OFFLINE fails. Memory is available again from
+  the section that we attempted to offline.
+
+MEMORY_OFFLINE

-ABOUT
------
-This file describes the new arch/mips/kernel/time.c, related files and the 
-services they provide. 
-
-If you are short in patience and just want to know how to use time.c for a 
-new board or convert an existing board, go to the last section.
-
-
-FILES, COMPATABILITY AND CONFIGS
----------------------------------
-
-The old arch/mips/kernel/time.c is renamed to old-time.c.
-
-A new time.c is put there, together with include/asm-mips/time.h.
-
-Two configs variables are introduced, CONFIG_OLD_TIME_C and CONFIG_NEW_TIME_C.
-So we allow boards using 
-
-	1) old time.c (CONFIG_OLD_TIME_C)
-	2) new time.c (CONFIG_NEW_TIME_C)
-	3) neither (their own private time.c)
-
-However, it is expected every board will move to the new time.c in the near
-future.
-
-
-WHAT THE NEW CODE PROVIDES?
---------------------------- 
-
-The new time code provide the following services:
-
-  a) Implements functions required by Linux common code:
-	time_init
-
-  b) provides an abstraction of RTC and null RTC implementation as default.
-	extern unsigned long (*rtc_get_time)(void);
-	extern int (*rtc_set_time)(unsigned long);
-
-  c) high-level and low-level timer interrupt routines where the timer
-     interrupt source  may or may not be the CPU timer.  The high-level
-     routine is dispatched through do_IRQ() while the low-level is
-     dispatched in assemably code (usually int-handler.S)

-For the new code to work properly, each board implementation needs to supply
-the following functions or values:
-
-  a) board_time_init - a function pointer.  Invoked at the beginnig of
-     time_init().  It is optional.
-	1. (optional) set up RTC routines
-	2. (optional) calibrate and set the mips_hpt_frequency
-
-  b) plat_timer_setup - a function pointer.  Invoked at the end of time_init()
-	1. (optional) over-ride any decisions made in time_init()
-	2. set up the irqaction for timer interrupt.
-	3. enable the timer interrupt
-
-  c) (optional) board-specific RTC routines.
-
-  d) (optional) mips_hpt_frequency - It must be definied if the board
-     is using CPU counter for timer interrupt.
-
-
-PORTING GUIDE
--------------
-
-Step 1: decide how you like to implement the time services.
-
-  a) does this board have a RTC?  If yes, implement the two RTC funcs.
-
-  b) does the CPU have counter/compare registers? 
-
-     If the answer is no, you need a timer to provide the timer interrupt
-     at 100 HZ speed.
-
-  c) The following sub steps assume your CPU has counter register.
-     Do you plan to use the CPU counter register as the timer interrupt
-     or use an exnternal timer?
-
-     In order to use CPU counter register as the timer interrupt source, you
-     must know the counter speed (mips_hpt_frequency).  It is usually the
-     same as the CPU speed or an integral divisor of it.
-
-  d) decide on whether you want to use high-level or low-level timer
-     interrupt routines.  The low-level one is presumably faster, but should
-     not make too mcuh difference.
-
-
-Step 2:  the machine setup() function
-
-  If you supply board_time_init(), set the function poointer.
-
-
-Step 3: implement rtc routines, board_time_init() and plat_timer_setup()
-  if needed.
-
-  board_time_init() -
-  	a) (optional) set up RTC routines,
-        b) (optional) calibrate and set the mips_hpt_frequency
- 	    (only needed if you intended to use cpu counter as timer interrupt
- 	     source)
-
-  plat_timer_setup() -
- 	a) (optional) over-write any choices made above by time_init().
- 	b) machine specific code should setup the timer irqaction.
- 	c) enable the timer interrupt
-
-
-  If the RTC chip is a common chip, I suggest the routines are put under
-  arch/mips/libs.  For example, for DS1386 chip, one would create
-  rtc-ds1386.c under arch/mips/lib directory.  Add the following line to
-  the arch/mips/lib/Makefile:
-
-	obj-$(CONFIG_DDB5476) += rtc-ds1386.o
-
-Step 4: if you are using low-level timer interrupt, change your interrupt
-  dispathcing code to check for timer interrupt and jump to 
-  ll_timer_interrupt() directly  if one is detected.
-
-Step 5: Modify arch/mips/config.in and add CONFIG_NEW_TIME_C to your machine.
-  Modify the appropriate defconfig if applicable.
-
-Final notes: 
-
-For some tricky cases, you may need to add your own wrapper functions 
-for some of the functions in time.c.  
-
-For example, you may define your own timer interrupt routine, which does
-some of its own processing and then calls timer_interrupt().
-
-You can also over-ride any of the built-in functions (RTC routines
-and/or timer interrupt routine).
-
-
-PORTING NOTES FOR SMP
-----------------------
-
-If you have a SMP box, things are slightly more complicated.
-
-The time service running every jiffy is logically divided into two parts:
-
-  1) the one for the whole system  (defined in timer_interrupt())
-  2) the one that should run for each CPU (defined in local_timer_interrupt())
-
-You need to decide on your timer interrupt sources.
-
-  case 1) - whole system has only one timer interrupt delivered to one CPU
-
-	In this case, you set up timer interrupt as in UP systems.  In addtion,
-	you need to set emulate_local_timer_interrupt to 1 so that other
-	CPUs get to call local_timer_interrupt().
-
-	THIS IS CURRENTLY NOT IMPLEMNETED.  However, it is rather easy to write
-	one should such a need arise.  You simply make a IPI call.
-
-  case 2) - each CPU has a separate timer interrupt
-
-	In this case, you need to set up IRQ such that each of them will
-	call local_timer_interrupt().  In addition, you need to arrange
-	one and only one of them to call timer_interrupt().
-
-	You can also do the low-level version of those interrupt routines,
-	following similar dispatching routes described above.

+/* ROUTINES:	$$divI, $$divoI
+
+   Single precision divide for signed binary integers.
+
+   The quotient is truncated towards zero.
+   The sign of the quotient is the XOR of the signs of the dividend and
+   divisor.
+   Divide by zero is trapped.
+   Divide of -2**31 by -1 is trapped for $$divoI but not for $$divI.
+
+   INPUT REGISTERS:
+   .	arg0 ==	dividend
+   .	arg1 ==	divisor
+   .	mrp  == return pc
+   .	sr0  == return space when called externally
+
+   OUTPUT REGISTERS:

+   .	arg1 =	undefined
+   .	ret1 =	quotient
+
+   OTHER REGISTERS AFFECTED:
+   .	r1   =	undefined
+
+   SIDE EFFECTS:
+   .	Causes a trap under the following conditions:
+   .		divisor is zero  (traps with ADDIT,=  0,25,0)
+   .		dividend==-2**31  and divisor==-1 and routine is $$divoI
+   .				 (traps with ADDO  26,25,0)
+   .	Changes memory at the following places:

+/* TRUNCATED DIVISION BY SMALL INTEGERS
+
+   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
+   (with y fixed).
+
+   Let a = floor(z/y), for some choice of z.  Note that z will be
+   chosen so that division by z is cheap.
+
+   Let r be the remainder(z/y).  In other words, r = z - ay.
+
+   Now, our method is to choose a value for b such that
+
+   q'(x) = floor((ax+b)/z)
+
+   is equal to q(x) over as large a range of x as possible.  If the
+   two are equal over a sufficiently large range, and if it is easy to
+   form the product (ax), and it is easy to divide by z, then we can
+   perform the division much faster than the general division algorithm.
+
+   So, we want the following to be true:
+
+   .	For x in the following range:
+   .
+   .	    ky <= x < (k+1)y
+   .
+   .	implies that
+   .
+   .	    k <= (ax+b)/z < (k+1)
+
+   We want to determine b such that this is true for all k in the
+   range {0..K} for some maximum K.
+
+   Since (ax+b) is an increasing function of x, we can take each
+   bound separately to determine the "best" value for b.
+
+   (ax+b)/z < (k+1)	       implies
+
+   (a((k+1)y-1)+b < (k+1)z     implies
+
+   b < a + (k+1)(z-ay)	       implies
+
+   b < a + (k+1)r
+
+   This needs to be true for all k in the range {0..K}.  In
+   particular, it is true for k = 0 and this leads to a maximum
+   acceptable value for b.
+
+   b < a+r   or   b <= a+r-1
+
+   Taking the other bound, we have
+
+   k <= (ax+b)/z	       implies
+
+   k <= (aky+b)/z	       implies
+
+   k(z-ay) <= b		       implies
+
+   kr <= b
+
+   Clearly, the largest range for k will be achieved by maximizing b,
+   when r is not zero.	When r is zero, then the simplest choice for b
+   is 0.  When r is not 0, set
+
+   .	b = a+r-1
+
+   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
+   for all x in the range:
+
+   .	0 <= x < (K+1)y
+
+   We need to determine what K is.  Of our two bounds,
+
+   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.
+
+   The other bound is
+
+   .	kr <= b
+
+   This is always true if r = 0.  If r is not 0 (the usual case), then
+   K = floor((a+r-1)/r), is the maximum value for k.
+
+   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
+   answer for q(x) = floor(x/y) when x is in the range
+
+   (0,(K+1)y-1)	       K = floor((a+r-1)/r)
+
+   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
+   the formula for q'(x) yields the correct value of q(x) for all x
+   representable by a single word in HPPA.
+
+   We are also constrained in that computing the product (ax), adding
+   b, and dividing by z must all be done quickly, otherwise we will be
+   better off going through the general algorithm using the DS
+   instruction, which uses approximately 70 cycles.
+
+   For each y, there is a choice of z which satisfies the constraints
+   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
+   timing constraints for arbitrary y.	It seems that z being equal to
+   a power of 2 or a power of 2 minus 1 is as good as we can do, since
+   it minimizes the time to do division by z.  We want the choice of z
+   to also result in a value for (a) that minimizes the computation of
+   the product (ax).  This is best achieved if (a) has a regular bit
+   pattern (so the multiplication can be done with shifts and adds).
+   The value of (a) also needs to be less than 2**32 so the product is
+   always guaranteed to fit in 2 words.
+
+   In actual practice, the following should be done:
+
+   1) For negative x, you should take the absolute value and remember
+   .  the fact so that the result can be negated.  This obviously does
+   .  not apply in the unsigned case.
+   2) For even y, you should factor out the power of 2 that divides y
+   .  and divide x by it.  You can then proceed by dividing by the
+   .  odd factor of y.
+
+   Here is a table of some odd values of y, and corresponding choices
+   for z which are "good".
+
+    y	  z	  r	 a (hex)     max x (hex)
+
+    3	2**32	  1	55555555      100000001
+    5	2**32	  1	33333333      100000003
+    7  2**24-1	  0	  249249     (infinite)
+    9  2**24-1	  0	  1c71c7     (infinite)
+   11  2**20-1	  0	   1745d     (infinite)
+   13  2**24-1	  0	  13b13b     (infinite)
+   15	2**32	  1	11111111      10000000d
+   17	2**32	  1	 f0f0f0f      10000000f
+
+   If r is 1, then b = a+r-1 = a.  This simplifies the computation
+   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
+   then b = 0 is ok to use which simplifies (ax+b).
+
+   The bit patterns for 55555555, 33333333, and 11111111 are obviously
+   very regular.  The bit patterns for the other values of a above are:
+
+    y	   (hex)	  (binary)
+
+    7	  249249  001001001001001001001001  << regular >>
+    9	  1c71c7  000111000111000111000111  << regular >>
+   11	   1745d  000000010111010001011101  << irregular >>
+   13	  13b13b  000100111011000100111011  << irregular >>
+
+   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
+   too irregular to warrant using this method.
+
+   When z is a power of 2 minus 1, then the division by z is slightly
+   more complicated, involving an iterative solution.
+
+   The code presented here solves division by 1 through 17, except for
+   11 and 13. There are algorithms for both signed and unsigned
+   quantities given.

+
+   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
+   a loop body is executed until the tentative quotient is 0.  The
+   number of times the loop body is executed varies depending on the
+   dividend, but is never more than two times.	If the dividend is
+   less than the divisor, then the loop body is not executed at all.
+   Each iteration adds 4 cycles to the timings.

+   z = 2**24-1
+   r = z mod x = 0
+
+   so choose b = 0
+
+   Also, in order to divide by z = 2**24-1, we approximate by dividing
+   by (z+1) = 2**24 (which is easy), and then correcting.
+
+   (ax) = (z+1)q' + r
+   .	= zq' + (q'+r)
+
+   So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
+   Then the true remainder of (ax)/z is (q'+r).  Repeat the process
+   with this new remainder, adding the tentative quotients together,
+   until a tentative quotient is 0 (and then we are done).  There is
+   one last correction to be done.  It is possible that (q'+r) = z.
+   If so, then (q'+r)/(z+1) = 0 and it looks like we are done.	But,
+   in fact, we need to add 1 more to the quotient.  Now, it turns
+   out that this happens if and only if the original value x is
+   an exact multiple of y.  So, to avoid a three instruction test at
+   the end, instead use 1 instruction to add 1 to x at the beginning.  */

+
+/* TRUNCATED DIVISION BY SMALL INTEGERS
+
+   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
+   (with y fixed).
+
+   Let a = floor(z/y), for some choice of z.  Note that z will be
+   chosen so that division by z is cheap.
+
+   Let r be the remainder(z/y).  In other words, r = z - ay.
+
+   Now, our method is to choose a value for b such that
+
+   q'(x) = floor((ax+b)/z)
+
+   is equal to q(x) over as large a range of x as possible.  If the
+   two are equal over a sufficiently large range, and if it is easy to
+   form the product (ax), and it is easy to divide by z, then we can
+   perform the division much faster than the general division algorithm.
+
+   So, we want the following to be true:
+
+   .	For x in the following range:
+   .
+   .	    ky <= x < (k+1)y
+   .
+   .	implies that
+   .
+   .	    k <= (ax+b)/z < (k+1)
+
+   We want to determine b such that this is true for all k in the
+   range {0..K} for some maximum K.
+
+   Since (ax+b) is an increasing function of x, we can take each
+   bound separately to determine the "best" value for b.
+
+   (ax+b)/z < (k+1)	       implies
+
+   (a((k+1)y-1)+b < (k+1)z     implies
+
+   b < a + (k+1)(z-ay)	       implies
+
+   b < a + (k+1)r
+
+   This needs to be true for all k in the range {0..K}.  In
+   particular, it is true for k = 0 and this leads to a maximum
+   acceptable value for b.
+
+   b < a+r   or   b <= a+r-1
+
+   Taking the other bound, we have
+
+   k <= (ax+b)/z	       implies
+
+   k <= (aky+b)/z	       implies
+
+   k(z-ay) <= b		       implies
+
+   kr <= b
+
+   Clearly, the largest range for k will be achieved by maximizing b,
+   when r is not zero.	When r is zero, then the simplest choice for b
+   is 0.  When r is not 0, set
+
+   .	b = a+r-1
+
+   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
+   for all x in the range:
+
+   .	0 <= x < (K+1)y
+
+   We need to determine what K is.  Of our two bounds,
+
+   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.
+
+   The other bound is
+
+   .	kr <= b
+
+   This is always true if r = 0.  If r is not 0 (the usual case), then
+   K = floor((a+r-1)/r), is the maximum value for k.
+
+   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
+   answer for q(x) = floor(x/y) when x is in the range
+
+   (0,(K+1)y-1)	       K = floor((a+r-1)/r)
+
+   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
+   the formula for q'(x) yields the correct value of q(x) for all x
+   representable by a single word in HPPA.
+
+   We are also constrained in that computing the product (ax), adding
+   b, and dividing by z must all be done quickly, otherwise we will be
+   better off going through the general algorithm using the DS
+   instruction, which uses approximately 70 cycles.
+
+   For each y, there is a choice of z which satisfies the constraints
+   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
+   timing constraints for arbitrary y.	It seems that z being equal to
+   a power of 2 or a power of 2 minus 1 is as good as we can do, since
+   it minimizes the time to do division by z.  We want the choice of z
+   to also result in a value for (a) that minimizes the computation of
+   the product (ax).  This is best achieved if (a) has a regular bit
+   pattern (so the multiplication can be done with shifts and adds).
+   The value of (a) also needs to be less than 2**32 so the product is
+   always guaranteed to fit in 2 words.
+
+   In actual practice, the following should be done:
+
+   1) For negative x, you should take the absolute value and remember
+   .  the fact so that the result can be negated.  This obviously does
+   .  not apply in the unsigned case.
+   2) For even y, you should factor out the power of 2 that divides y
+   .  and divide x by it.  You can then proceed by dividing by the
+   .  odd factor of y.
+
+   Here is a table of some odd values of y, and corresponding choices
+   for z which are "good".
+
+    y	  z	  r	 a (hex)     max x (hex)
+
+    3	2**32	  1	55555555      100000001
+    5	2**32	  1	33333333      100000003
+    7  2**24-1	  0	  249249     (infinite)
+    9  2**24-1	  0	  1c71c7     (infinite)
+   11  2**20-1	  0	   1745d     (infinite)
+   13  2**24-1	  0	  13b13b     (infinite)
+   15	2**32	  1	11111111      10000000d
+   17	2**32	  1	 f0f0f0f      10000000f
+
+   If r is 1, then b = a+r-1 = a.  This simplifies the computation
+   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
+   then b = 0 is ok to use which simplifies (ax+b).
+
+   The bit patterns for 55555555, 33333333, and 11111111 are obviously
+   very regular.  The bit patterns for the other values of a above are:
+
+    y	   (hex)	  (binary)
+
+    7	  249249  001001001001001001001001  << regular >>
+    9	  1c71c7  000111000111000111000111  << regular >>
+   11	   1745d  000000010111010001011101  << irregular >>
+   13	  13b13b  000100111011000100111011  << irregular >>
+
+   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
+   too irregular to warrant using this method.
+
+   When z is a power of 2 minus 1, then the division by z is slightly
+   more complicated, involving an iterative solution.
+
+   The code presented here solves division by 1 through 17, except for
+   11 and 13. There are algorithms for both signed and unsigned
+   quantities given.

+
+   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
+   a loop body is executed until the tentative quotient is 0.  The
+   number of times the loop body is executed varies depending on the
+   dividend, but is never more than two times.	If the dividend is
+   less than the divisor, then the loop body is not executed at all.
+   Each iteration adds 4 cycles to the timings.

+
+   z = 2**24-1
+   r = z mod x = 0
+
+   so choose b = 0
+
+   Also, in order to divide by z = 2**24-1, we approximate by dividing
+   by (z+1) = 2**24 (which is easy), and then correcting.
+
+   (ax) = (z+1)q' + r
+   .	= zq' + (q'+r)
+
+   So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
+   Then the true remainder of (ax)/z is (q'+r).  Repeat the process
+   with this new remainder, adding the tentative quotients together,
+   until a tentative quotient is 0 (and then we are done).  There is
+   one last correction to be done.  It is possible that (q'+r) = z.
+   If so, then (q'+r)/(z+1) = 0 and it looks like we are done.	But,
+   in fact, we need to add 1 more to the quotient.  Now, it turns
+   out that this happens if and only if the original value x is
+   an exact multiple of y.  So, to avoid a three instruction test at
+   the end, instead use 1 instruction to add 1 to x at the beginning.  */

+/* ROUTINE:	$$remI
+
+   DESCRIPTION:
+   .	$$remI returns the remainder of the division of two signed 32-bit
+   .	integers.  The sign of the remainder is the same as the sign of
+   .	the dividend.
+
+
+   INPUT REGISTERS:
+   .	arg0 == dividend
+   .	arg1 == divisor
+   .	mrp  == return pc
+   .	sr0  == return space when called externally
+
+   OUTPUT REGISTERS:
+   .	arg0 = destroyed
+   .	arg1 = destroyed
+   .	ret1 = remainder
+
+   OTHER REGISTERS AFFECTED:
+   .	r1   = undefined
+
+   SIDE EFFECTS:
+   .	Causes a trap under the following conditions:  DIVIDE BY ZERO
+   .	Changes memory at the following places:  NONE
+
+   PERMISSIBLE CONTEXT:
+   .	Unwindable
+   .	Does not create a stack frame
+   .	Is usable for internal or external microcode
+
+   DISCUSSION:
+   .	Calls other millicode routines via mrp:  NONE
+   .	Calls other millicode routines:  NONE  */

- * The Guest console driver
- *
- * This is a trivial console driver: we use lguest's DMA mechanism to send
- * bytes out, and register a DMA buffer to receive bytes in.  It is assumed to
- * be present and available from the very beginning of boot.
- *
- * Writing console drivers is one of the few remaining Dark Arts in Linux.
- * Fortunately for us, the path of virtual consoles has been well-trodden by
- * the PowerPC folks, who wrote "hvc_console.c" to generically support any
- * virtual console.  We use that infrastructure which only requires us to write
- * the basic put_chars and get_chars functions and call the right register
- * functions.
- :*/
-
-/*M:002 The console can be flooded: while the Guest is processing input the
- * Host can send more.  Buffering in the Host could alleviate this, but it is a
- * difficult problem in general. :*/

- * visitation in the middle of the Linux code, and yet make sure that Guests
- * can talk directly to other Guests, not just the Launcher.
- *
- * To do this, the Guest gives us a key when it binds or sends DMA buffers.
- * The key corresponds to a "physical" address inside the Guest (ie. a virtual
- * address inside the Launcher process).  We don't, however, use this key
- * directly.
- *
- * We want Guests which share memory to be able to DMA to each other: two
- * Launchers can mmap memory the same file, then the Guests can communicate.
- * Fortunately, the futex code provides us with a way to get a "union
- * futex_key" corresponding to the memory lying at a virtual address: if the
- * two processes share memory, the "union futex_key" for that memory will match
- * even if the memory is mapped at different addresses in each.  So we always
- * convert the keys to "union futex_key"s to compare them.

- * Firstly, it doesn't use "NAPI": the networking's New API, and is poorer for

- * network interfaces.  Lack of NAPI can mean competition at higher loads."
- *
- * He also points out that we don't implement set_mac_address, so users cannot
- * change the devices hardware address.  When I asked why one would want to:
- * "Bonding, and situations where you /do/ want the MAC address to "leak" out
- * of the host onto the wider net."
- *
- * Finally, he would like module unloading: "It is not unrealistic to think of
- * [un|re|]loading the net support module in an lguest guest.  And, adding
- * module support makes the programmer more responsible, because they now have
- * to learn to clean up after themselves.  Any driver that cannot clean up

-/**
- * find_exported_dentry - helper routine to implement export_operations->decode_fh
- * @sb:		The &super_block identifying the filesystem
- * @obj:	An opaque identifier of the object to be found - passed to
- *		get_inode
- * @parent:	An optional opqaue identifier of the parent of the object.
- * @acceptable:	A function used to test possible &dentries to see if they are
- *		acceptable
- * @context:	A parameter to @acceptable so that it knows on what basis to
- *		judge.
- *
- * find_exported_dentry is the central helper routine to enable file systems
- * to provide the decode_fh() export_operation.  It's main task is to take
- * an &inode, find or create an appropriate &dentry structure, and possibly
- * splice this into the dcache in the correct place.
- *
- * The decode_fh() operation provided by the filesystem should call
- * find_exported_dentry() with the same parameters that it received except
- * that instead of the file handle fragment, pointers to opaque identifiers
- * for the object and optionally its parent are passed.  The default decode_fh
- * routine passes one pointer to the start of the filehandle fragment, and
- * one 8 bytes into the fragment.  It is expected that most filesystems will
- * take this approach, though the offset to the parent identifier may well be
- * different.
- *
- * find_exported_dentry() will call get_dentry to get an dentry pointer from
- * the file system.  If any &dentry in the d_alias list is acceptable, it will
- * be returned.  Otherwise find_exported_dentry() will attempt to splice a new
- * &dentry into the dcache using get_name() and get_parent() to find the
- * appropriate place.

  * @get_name:       find the name for a given inode in a given directory
  * @get_parent:     find the parent of a given directory
  * @get_dentry:     find a dentry for the inode given a file handle sub-fragment
- * @find_exported_dentry:

- *
- * Description:
- *    The export_operations structure provides a means for nfsd to communicate
- *    with a particular exported file system  - particularly enabling nfsd and
- *    the filesystem to co-operate when dealing with file handles.
- *
- *    export_operations contains two basic operation for dealing with file
- *    handles, decode_fh() and encode_fh(), and allows for some other
- *    operations to be defined which standard helper routines use to get
- *    specific information from the filesystem.
- *
- *    nfsd encodes information use to determine which filesystem a filehandle
- *    applies to in the initial part of the file handle.  The remainder, termed
- *    a file handle fragment, is controlled completely by the filesystem.  The
- *    standard helper routines assume that this fragment will contain one or
- *    two sub-fragments, one which identifies the file, and one which may be
- *    used to identify the (a) directory containing the file.
  *
- *    In some situations, nfsd needs to get a dentry which is connected into a
- *    specific part of the file tree.  To allow for this, it passes the
- *    function acceptable() together with a @context which can be used to see
- *    if the dentry is acceptable.  As there can be multiple dentrys for a
- *    given file, the filesystem should check each one for acceptability before
- *    looking for the next.  As soon as an acceptable one is found, it should
- *    be returned.
- *
- * decode_fh:
- *    @decode_fh is given a &struct super_block (@sb), a file handle fragment
- *    (@fh, @fh_len) and an acceptability testing function (@acceptable,
- *    @context).  It should return a &struct dentry which refers to the same
- *    file that the file handle fragment refers to,  and which passes the
- *    acceptability test.  If it cannot, it should return a %NULL pointer if
- *    the file was found but no acceptable &dentries were available, or a
- *    %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or
- *    %ENOMEM).
+ * See Documentation/filesystems/Exporting for details on how to use

- * Lguest I/O
- *
- * The lguest I/O mechanism is the only way Guests can talk to devices.  There
- * are two hypercalls involved: SEND_DMA for output and BIND_DMA for input.  In
- * each case, "struct lguest_dma" describes the buffer: this contains 16
- * addr/len pairs, and if there are fewer buffer elements the len array is
- * terminated with a 0.
- *
- * I/O is organized by keys: BIND_DMA attaches buffers to a particular key, and
- * SEND_DMA transfers to buffers bound to particular key.  By convention, keys
- * correspond to a physical address within the device's page.  This means that
- * devices will never accidentally end up with the same keys, and allows the
- * Host use The Futex Trick (as we'll see later in our journey).
- *
- * SEND_DMA simply indicates a key to send to, and the physical address of the
- * "struct lguest_dma" to send.  The Host will write the number of bytes
- * transferred into the "struct lguest_dma"'s used_len member.
- *
- * BIND_DMA indicates a key to bind to, a pointer to an array of "struct
- * lguest_dma"s ready for receiving, the size of that array, and an interrupt
- * to trigger when data is received.  The Host will only allow transfers into
- * buffers with a used_len of zero: it then sets used_len to the number of
- * bytes transferred and triggers the interrupt for the Guest to process the

- *	@set_target() is executed right prior to suspending devices.  The
- *	information conveyed to the platform code by @set_target() should be
- *	disregarded by the platform as soon as @finish() is executed and if
- *	@prepare() fails.  If @set_target() fails (ie. returns nonzero),
- *	@prepare(), @enter() and @finish() will not be called by the PM core.

- *	passed to @prepare(), @enter() and @finish() is meaningless and should

+ * struct platform_suspend_ops - Callbacks for managing platform dependent
+ *	system sleep states.
+ *
+ * @valid: Callback to determine if given system sleep state is supported by
+ *	the platform.
+ *	Valid (ie. supported) states are advertised in /sys/power/state.  Note
+ *	that it still may be impossible to enter given system sleep state if the
+ *	conditions aren't right.
+ *	There is the %suspend_valid_only_mem function available that can be
+ *	assigned to this if the platform only supports mem sleep.
+ *
+ * @set_target: Tell the platform which system sleep state is going to be
+ *	entered.
+ *	@set_target() is executed right prior to suspending devices.  The
+ *	information conveyed to the platform code by @set_target() should be
+ *	disregarded by the platform as soon as @finish() is executed and if
+ *	@prepare() fails.  If @set_target() fails (ie. returns nonzero),
+ *	@prepare(), @enter() and @finish() will not be called by the PM core.
+ *	This callback is optional.  However, if it is implemented, the argument
+ *	passed to @enter() is meaningless and should be ignored.
+ *
+ * @prepare: Prepare the platform for entering the system sleep state indicated
+ *	by @set_target().
+ *	@prepare() is called right after devices have been suspended (ie. the
+ *	appropriate .suspend() method has been executed for each device) and
+ *	before the nonboot CPUs are disabled (it is executed with IRQs enabled).
+ *	This callback is optional.  It returns 0 on success or a negative
+ *	error code otherwise, in which case the system cannot enter the desired
+ *	sleep state (@enter() and @finish() will not be called in that case).
+ *
+ * @enter: Enter the system sleep state indicated by @set_target() or
+ *	represented by the argument if @set_target() is not implemented.
+ *	This callback is mandatory.  It returns 0 on success or a negative
+ *	error code otherwise, in which case the system cannot enter the desired
+ *	sleep state.
+ *
+ * @finish: Called when the system has just left a sleep state, right after
+ *	the nonboot CPUs have been enabled and before devices are resumed (it is
+ *	executed with IRQs enabled).
+ *	This callback is optional, but should be implemented by the platforms
+ *	that implement @prepare().  If implemented, it is always called after
+ *	@enter() (even if @enter() fails).

  *
- * @prepare: prepare system for hibernation
- * @enter: shut down system after state has been saved to disk

- * @pre_restore: prepare system for the restoration from a hibernation image
- * @restore_cleanup: clean up after a failing image restoration
+ * @start: Tell the platform driver that we're starting hibernation.
+ *	Called right after shrinking memory and before freezing devices.
+ *
+ * @pre_snapshot: Prepare the platform for creating the hibernation image.
+ *	Called right after devices have been frozen and before the nonboot
+ *	CPUs are disabled (runs with IRQs on).
+ *
+ * @finish: Restore the previous state of the platform after the hibernation
+ *	image has been created *or* put the platform into the normal operation
+ *	mode after the hibernation (the same method is executed in both cases).
+ *	Called right after the nonboot CPUs have been enabled and before

+ *	devices are prepared for entering the low power state.
+ *
+ * @enter: Put the system into the low power state after the hibernation image
+ *	has been saved to disk.
+ *	Called after the nonboot CPUs have been disabled and all of the low
+ *	level devices have been shut down (runs with IRQs off).
+ *
+ * @leave: Perform the first stage of the cleanup after the system sleep state
+ *	indicated by @set_target() has been left.
+ *	Called right after the control has been passed from the boot kernel to
+ *	the image kernel, before the nonboot CPUs are enabled and before devices
+ *	are resumed.  Executed with interrupts disabled.
+ *
+ * @pre_restore: Prepare system for the restoration from a hibernation image.

+ * There is one global cgroup mutex. We also require taking
+ * task_lock() when dereferencing a task's cgroup subsys pointers.
+ * See "The task_lock() exception", at the end of this comment.
+ *
+ * A task must hold cgroup_mutex to modify cgroups.
+ *
+ * Any task can increment and decrement the count field without lock.
+ * So in general, code holding cgroup_mutex can't rely on the count
+ * field not changing.  However, if the count goes to zero, then only
+ * attach_task() can increment it again.  Because a count of zero
+ * means that no tasks are currently attached, therefore there is no
+ * way a task attached to that cgroup can fork (the other way to
+ * increment the count).  So code holding cgroup_mutex can safely
+ * assume that if the count is zero, it will stay zero. Similarly, if
+ * a task holds cgroup_mutex on a cgroup with zero count, it
+ * knows that the cgroup won't be removed, as cgroup_rmdir()
+ * needs that mutex.
+ *
+ * The cgroup_common_file_write handler for operations that modify
+ * the cgroup hierarchy holds cgroup_mutex across the entire operation,
+ * single threading all such cgroup modifications across the system.
+ *
+ * The fork and exit callbacks cgroup_fork() and cgroup_exit(), don't
+ * (usually) take cgroup_mutex.  These are the two most performance
+ * critical pieces of code here.  The exception occurs on cgroup_exit(),
+ * when a task in a notify_on_release cgroup exits.  Then cgroup_mutex
+ * is taken, and if the cgroup count is zero, a usermode call made
+ * to /sbin/cgroup_release_agent with the name of the cgroup (path
+ * relative to the root of cgroup file system) as the argument.
+ *
+ * A cgroup can only be deleted if both its 'count' of using tasks
+ * is zero, and its list of 'children' cgroups is empty.  Since all
+ * tasks in the system use _some_ cgroup, and since there is always at
+ * least one task in the system (init, pid == 1), therefore, top_cgroup
+ * always has either children cgroups and/or using tasks.  So we don't
+ * need a special hack to ensure that top_cgroup cannot be deleted.
+ *
+ *	The task_lock() exception
+ *
+ * The need for this exception arises from the action of
+ * attach_task(), which overwrites one tasks cgroup pointer with
+ * another.  It does so using cgroup_mutexe, however there are
+ * several performance critical places that need to reference
+ * task->cgroup without the expense of grabbing a system global
+ * mutex.  Therefore except as noted below, when dereferencing or, as
+ * in attach_task(), modifying a task'ss cgroup pointer we use
+ * task_lock(), which acts on a spinlock (task->alloc_lock) already in
+ * the task_struct routinely used for such matters.
+ *
+ * P.S.  One more locking exception.  RCU is used to guard the
+ * update of a tasks cgroup pointer by attach_task()

+ * scheduler's dynamic sched domains.
+ *
+ * This routine builds a partial partition of the systems CPUs
+ * (the set of non-overlappping cpumask_t's in the array 'part'
+ * below), and passes that partial partition to the kernel/sched.c
+ * partition_sched_domains() routine, which will rebuild the
+ * schedulers load balancing domains (sched domains) as specified
+ * by that partial partition.  A 'partial partition' is a set of
+ * non-overlapping subsets whose union is a subset of that set.
+ *
+ * See "What is sched_load_balance" in Documentation/cpusets.txt
+ * for a background explanation of this.
+ *
+ * Does not return errors, on the theory that the callers of this
+ * routine would rather not worry about failures to rebuild sched
+ * domains when operating in the severe memory shortage situations
+ * that could cause allocation failures below.
+ *
+ * Call with cgroup_mutex held.  May take callback_mutex during
+ * call due to the kfifo_alloc() and kmalloc() calls.  May nest
+ * a call to the lock_cpu_hotplug()/unlock_cpu_hotplug() pair.
+ * Must not be called holding callback_mutex, because we must not
+ * call lock_cpu_hotplug() while holding callback_mutex.  Elsewhere
+ * the kernel nests callback_mutex inside lock_cpu_hotplug() calls.
+ * So the reverse nesting would risk an ABBA deadlock.
+ *
+ * The three key local variables below are:
+ *    q  - a kfifo queue of cpuset pointers, used to implement a
+ *	   top-down scan of all cpusets.  This scan loads a pointer
+ *	   to each cpuset marked is_sched_load_balance into the
+ *	   array 'csa'.  For our purposes, rebuilding the schedulers
+ *	   sched domains, we can ignore !is_sched_load_balance cpusets.
+ *  csa  - (for CpuSet Array) Array of pointers to all the cpusets
+ *	   that need to be load balanced, for convenient iterative
+ *	   access by the subsequent code that finds the best partition,
+ *	   i.e the set of domains (subsets) of CPUs such that the
+ *	   cpus_allowed of every cpuset marked is_sched_load_balance
+ *	   is a subset of one of these domains, while there are as
+ *	   many such domains as possible, each as small as possible.
+ * doms  - Conversion of 'csa' to an array of cpumasks, for passing to
+ *	   the kernel/sched.c routine partition_sched_domains() in a
+ *	   convenient format, that can be easily compared to the prior
+ *	   value to determine what partition elements (sched domains)
+ *	   were changed (added or removed.)
+ *
+ * Finding the best partition (set of domains):
+ *	The triple nested loops below over i, j, k scan over the
+ *	load balanced cpusets (using the array of cpuset pointers in
+ *	csa[]) looking for pairs of cpusets that have overlapping
+ *	cpus_allowed, but which don't have the same 'pn' partition
+ *	number and gives them in the same partition number.  It keeps
+ *	looping on the 'restart' label until it can no longer find
+ *	any such pairs.
+ *
+ *	The union of the cpus_allowed masks from the set of

- * be removed and freed.  Instead, we task_lock(current) and copy
- * its present value of current->cpuset for our freshly forked child.

- * cpuset_exit - detach cpuset from exiting task
- * @tsk: pointer to task_struct of exiting process
- *
- * Description: Detach cpuset from @tsk and release it.
- *
- * Note that cpusets marked notify_on_release force every task in
- * them to take the global manage_mutex mutex when exiting.
- * This could impact scaling on very large systems.  Be reluctant to
- * use notify_on_release cpusets where very high task exit scaling
- * is required on large systems.
- *
- * Don't even think about derefencing 'cs' after the cpuset use count
- * goes to zero, except inside a critical section guarded by manage_mutex
- * or callback_mutex.   Otherwise a zero cpuset use count is a license to
- * any other task to nuke the cpuset immediately, via cpuset_rmdir().
- *
- * This routine has to take manage_mutex, not callback_mutex, because
- * it is holding that mutex while calling check_for_release(),
- * which calls kmalloc(), so can't be called holding callback_mutex().
- *
- * the_top_cpuset_hack:
- *
- *    Set the exiting tasks cpuset to the root cpuset (top_cpuset).
- *
- *    Don't leave a task unable to allocate memory, as that is an
- *    accident waiting to happen should someone add a callout in
- *    do_exit() after the cpuset_exit() call that might allocate.
- *    If a task tries to allocate memory with an invalid cpuset,
- *    it will oops in cpuset_update_task_memory_state().
- *
- *    We call cpuset_exit() while the task is still competent to
- *    handle notify_on_release(), then leave the task attached to
- *    the root cpuset (top_cpuset) for the remainder of its exit.
- *
- *    To do this properly, we would increment the reference count on
- *    top_cpuset, and near the very end of the kernel/exit.c do_exit()
- *    code we would add a second cpuset function call, to drop that
- *    reference.  This would just create an unnecessary hot spot on
- *    the top_cpuset reference count, to no avail.
- *
- *    Normally, holding a reference to a cpuset without bumping its
- *    count is unsafe.   The cpuset could go away, or someone could
- *    attach us to a different cpuset, decrementing the count on
- *    the first cpuset that we never incremented.  But in this case,
- *    top_cpuset isn't going away, and either task has PF_EXITING set,
- *    which wards off any attach_task() attempts, or task is a failed
- *    fork, never visible to attach_task.
- *
- *    Another way to do this would be to set the cpuset pointer
- *    to NULL here, and check in cpuset_update_task_memory_state()
- *    for a NULL pointer.  This hack avoids that NULL check, for no
- *    cost (other than this way too long comment ;).

- *
- *	26/01/2001 ed 0.1 Iain Sandoe
- *		- added version info.
- *		- moved dbdma command buffer allocation to PMacXXXSqSetup()
- *		- fixed up beep dbdma cmd buffers
- *
- *	08/02/2001 [0.2]
- *		- make SNDCTL_DSP_GETFMTS return the correct info for the h/w
- *		- move soft format translations to a separate file
- *		- [0.3] make SNDCTL_DSP_GETCAPS return correct info.
- *		- [0.4] more informative machine name strings.
- *		- [0.5]
- *		- record changes.
- *		- made the default_hard/soft entries.
- *	04/04/2001 [0.6]
- *		- minor correction to bit assignments in awacs_defs.h
- *		- incorporate mixer changes from 2.2.x back-port.
- *		- take out passthru as a rec input (it isn't).
- *              - make Input Gain slider work the 'right way up'.
- *              - try to make the mixer sliders more logical - so now the
- *                input selectors are just two-state (>50% == ON) and the
- *                Input Gain slider handles the rest of the gain issues.
- *              - try to pick slider representations that most closely match
- *                the actual use - e.g. IGain for input gain... 
- *              - first stab at over/under-run detection.
- *		- minor cosmetic changes to IRQ identification.
- *		- fix bug where rates > max would be reported as supported.
- *              - first stab at over/under-run detection.
- *              - make use of i2c for mixer settings conditional on perch
- *                rather than cuda (some machines without perch have cuda).
- *              - fix bug where TX stops when dbdma status comes up "DEAD"
- *		  so far only reported on PowerComputing clones ... but.
- *		- put in AWACS/Screamer register write timeouts.

- *	        - Support for snapper & better tumbler integration by Toby Sargeant
- *	        - Headphone detect for scremer by Julien Blache

-   When DEAD status is first reported the content of the faulted dbdma block is

-   xfers when the number of residual bytes gets below a certain value - I can
-   see that this might cause a loop-forever if too small a transfer causes
-   DEAD status.  However this is a TODO for now - we'll see what gets reported.
-   When we get a successful transfer result with the emergency buffer we just
-   pretend that it completed using the original dmdma_cmd and carry on.  The

- *   * Implement sleep support (at least mute everything and
- *   * set gains to minimum during sleep)
- *   * Look into some of Darwin's tweaks regarding the mute
- *   * lines (delays & different behaviour on some HW)

- *
- * Special thanks to Ensoniq
- *
- *  Supported devices:
- *  /dev/dsp    standard /dev/dsp device, (mostly) OSS compatible
- *  /dev/mixer  standard /dev/mixer device, (mostly) OSS compatible
- *  /dev/dsp1   additional DAC, like /dev/dsp, but outputs to mixer "SYNTH" setting
- *  /dev/midi   simple MIDI UART interface, no ioctl
- *
- *  NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
- *  to be done in software. That is what /dev/dac is for. By now (Q2 1998)
- *  there are several MIDI to PCM (WAV) packages, one of them is timidity.
- *
- *  Revision history
- *    04.06.1998   0.1   Initial release
- *                       Mixer stuff should be overhauled; especially optional AC97 mixer bits
- *                       should be detected. This results in strange behaviour of some mixer
- *                       settings, like master volume and mic.
- *    08.06.1998   0.2   First release using Alan Cox' soundcore instead of miscdevice
- *    03.08.1998   0.3   Do not include modversions.h
- *                       Now mixer behaviour can basically be selected between
- *                       "OSS documented" and "OSS actual" behaviour
- *    31.08.1998   0.4   Fix realplayer problems - dac.count issues
- *    27.10.1998   0.5   Fix joystick support
- *                       -- Oliver Neukum (c188@org.chemie.uni-muenchen.de)
- *    10.12.1998   0.6   Fix drain_dac trying to wait on not yet initialized DMA
- *    23.12.1998   0.7   Fix a few f_file & FMODE_ bugs
- *                       Don't wake up app until there are fragsize bytes to read/write
- *    06.01.1999   0.8   remove the silly SA_INTERRUPT flag.
- *                       hopefully killed the egcs section type conflict
- *    12.03.1999   0.9   cinfo.blocks should be reset after GETxPTR ioctl.
- *                       reported by Johan Maes <joma@telindus.be>
- *    22.03.1999   0.10  return EAGAIN instead of EBUSY when O_NONBLOCK
- *                       read/write cannot be executed
- *    07.04.1999   0.11  implemented the following ioctl's: SOUND_PCM_READ_RATE, 
- *                       SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS; 
- *                       Alpha fixes reported by Peter Jones <pjones@redhat.com>
- *                       Another Alpha fix (wait_src_ready in init routine)
- *                       reported by "Ivan N. Kokshaysky" <ink@jurassic.park.msu.ru>
- *                       Note: joystick address handling might still be wrong on archs
- *                       other than i386
- *    15.06.1999   0.12  Fix bad allocation bug.
- *                       Thanks to Deti Fliegl <fliegl@in.tum.de>
- *    28.06.1999   0.13  Add pci_set_master
- *    03.08.1999   0.14  adapt to Linus' new __setup/__initcall

- *                       Added detection for ES1371 revision ID so that we can
- *                       detect the ES1373 and later parts.
- *                       added AC97 #defines for readability
- *                       added a /proc file system for dumping hardware state
- *                       updated SRC and CODEC w/r functions to accommodate bugs
- *                       in some versions of the ES137x chips.
