The function shouldn't have existed in the first place (not MSS-aware). Introduce a new function ccw_device_get_id() that extracts the ccw_dev_id structure of a ccw device and convert all users of _ccw_device_get_device_number to ccw_device_get_id.

2007-05-10[POWERPC] Fix compile error with kexec and CONFIG_SMP=nPaul Mackerras1-0/+1
Commit 2f4dfe206a2fc07099dfad77a8ea2f4b4ae2140f moved the definition of hard_smp_processor_id() for the UP case from include/linux/smp.h to include/asm/smp.h. However, include/linux/smp.h only includes include/asm/smp.h in the SMP case, so code that wants to use hard_smp_processor_id() has to include <asm/smp.h> explicitly to be sure of getting the definition.

2007-05-10[POWERPC] Split initrd logic out of early_init_dt_scan_chosen() to fix warningMichael Ellerman1-16/+31
If CONFIG_BLK_DEV_INITRD is not defined the prop variable in early_init_dt_scan_chosen() is unused, causing a compiler warning. So split the initrd logic into a separate function, allowing us to declare prop only when we need it. Built for both cases and booted with an initrd.

2007-05-10[POWERPC] Fix warning in hpte_decode(), and generalize itPaul Mackerras2-21/+28
This adds the necessary support to hpte_decode() to handle 1TB segments and 16GB pages, and removes an uninitialized value warning on avpn. We don't have any code to generate HPTEs for 1TB segments or 16GB pages yet, so this is mostly for completeness, and to fix the warning.

2007-05-10[POWERPC] Fix incorrect calculation of I/O window addressesPaul Mackerras1-24/+13
My patch "Cope with PCI host bridge I/O window not starting at 0" introduced a bug in the calculation of the virtual addresses for the I/O windows of PCI host bridges other than the first, because it didn't account for the fact that hose->io_resource gets offset so that it reflects the range of global I/O port numbers assigned to the bridge. This fixes it and simplifies get_bus_io_range() in the process. Signed-off-by: Paul Mackerras <paulus@samba.org>

Celleb has multiple PCI host bridges (phbs). Previous boot logic gives non-overlapped bus IDs between PCI host bridges so you can identify PHB by bus ID. But newer boot logic gives same bus ID between PHBs (it gives bus ID 0 as root bus.) So we have to set 'phb->buid' as non-zero.

2007-05-10acpi,msi-laptop: Fall back to EC polling mode for MSI laptop specific EC ↵Lennart Poettering3-23/+31
commands The ACPI EC that is used in MSI laptops knows some non-standard commands for changing the screen brighntess and a few other things, which are used by the msi-laptop.c driver. Unfortunately for these commands no GPE events for IBF and OBF are triggered. Since nowadays the EC code uses the ec_intr=1 mode by default, this causes these operations to timeout, although they don't fail. In result, all operations that you can do with the msi-laptop.c driver take more or less 1s to complete, which is awfully slow. In one of the more recent kernels (2.6.20?) the EC subsystem has been revamped. With that change the EC timeout has been increased. before that increase the MSI EC accesses were slow -- but not *that* slow, hence I took notice of this limitation of the MSI EC hardware only very recently. The standard EC operations on the MSI EC as defined in the ACPI spec support GPE events properly. The following patch adds a new argument "force_poll" to the ec_transaction() function (and friends). If set to 1, the function will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the current behaviour is used. The msi-laptop driver is modified to make use of this new flag, so that OBF/IBF is polled for the special MSI EC transactions -- but only for them.

2007-05-09[POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi17-217/+221
The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

2007-05-09ACPI: created a dedicated workqueue for notify() executionAlexey Starikovskiy1-10/+35
HP nx6125/nx6325/... machines have a _GPE handler with an infinite loop sending Notify() events to different ACPI subsystems. Notify handler in ACPI driver is a C-routine, which may call ACPI interpreter again to get access to some ACPI variables (acpi_evaluate_xxx). On these HP machines such an evaluation changes state of some variable and lets the loop above break. In the current ACPI implementation Notify requests are being deferred to the same kacpid workqueue on which the above GPE handler with infinite loop is executing. Thus we have a deadlock -- loop will continue to spin, sending notify events, and at the same time preventing these notify events from being run on a workqueue. All notify events are deferred, thus we see increase in memory consumption noticed by author of the thread. Also as GPE handling is bloked, machines overheat. Eventually by external poll of the same acpi_evaluate, kacpid is released and all the queued notify events are free to run, thus 100% cpu utilization by kacpid for several seconds or more. To prevent all these horrors it's needed to not put notify events to kacpid workqueue by either executing them immediately or putting them on some other thread. It's dangerous to execute notify events in place, as it will put several ACPI interpreter stacks on top of each other (at least 4 in case of nx6125), thus causing kernel stack overflow. First attempt to create a new thread was done by Peter Wainwright He created a bunch of threads, which were stealing work from a kacpid workqueue. This patch appeared in 2.6.15 kernel shipped with Ubuntu 6.06 LTS. Second attempt was done by me, I created a new thread for each Notify event. This worked OK on HP nx machines, but broke Linus' Compaq n620c, by producing threads with a speed what they stopped the machine completely. Thus this patch was reverted from 18-rc2 as I remember. I re-made the patch to create second workqueue just for notify events, thus hopping it will not break Linus' machine. Patch was tested on the same HP nx machines in #5534 and #7122, but I did not received reply from Linus on a test patch sent to him. Patch went to 19-rc and was rejected with much fanfare again. There was 4th patch, which inserted schedule_timeout(1) into deferred execution of kacpid, if we had any notify requests pending, but Linus decided that it was too complex (involved either changes to workqueue to see if it's empty or atomic inc/dec). Now you see last variant which adds yield() to every GPE execution. http://bugzilla.kernel.org/show_bug.cgi?id=5534 http://bugzilla.kernel.org/show_bug.cgi?id=8385 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2007-05-09Revert "ACPICA: fix AML mutex re-entrancy"Len Brown6-25/+31
This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877. These changes to AML locking were made to allow Notify handlers to be called on the stack and not deadlock.

While that change fixed the HP http://bugzilla.kernel.org/show_bug.cgi?id=5534 it broke the ACER: http://bugzilla.kernel.org/show_bug.cgi?id=8385 which as AML that caused Linux go recursive and stack fault. So this commit by itself will restore the ACER and again break the HP, which we'll fix another way. Signed-off-by: Len Brown <len.brown@intel.com>
