Use dev_pm_ops instead of legacy suspend/resume callbacks for IIO drivers.
Note that this patch introduces a few new #ifdef CONFIG_PM_SLEEP around the
suspend and resume callbacks to avoid warnings of unused functions if
CONFIG_PM_SLEEP is not defined.

Lifted from proposal for in kernel interface built on the out of staging
branch.
Two elements here:
* Map as defined in "inkern.h"
* Matching code to actually get the iio_dev and channel
that we want from the global list of IIO devices.
V4: Everything now built if iio is built (rather than being optional)
Removal race condition prevented by using info pointer as a check
of removal under a lock.
V3: Drop the option of registering / getting channels using dev pointer.
Stick to name only as suggested by Mark Brown (this has caused user
confusion in the regulator framework.)
V2: As per Greg KH suggestion, move over to registration by passing
the tables into the provider drivers (how regulator does it).
This does not prevent us using the original more flexible approach
if at a later date there is a usecase that demands it.

This prevents use of provider callbacks after it has been unregistered.
Note that all code using this that can be called from a consumer *must*
check the pointer before using and hold the info_exist_lock throughout
the usage of the callbacks in info.

In order to detect WDT feature on the dsp code, we need to
find the symbol used to enable it inside the baseimage.
This should fix the warning comming from L3 driver:
WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:161 omap3_l3_app_irq...
In-band Error seen by IVA_SS at address 0
...
That occurs because the dsp tries to access wdt3 registers when the clock
for those registers is not enabled.

In order to detect it at runtime, we need the code handling wdt
clock available at runtime to decide whether to enable or disable
based on the baseimage symbols. Default timeout has been set to 5
seconds.
Downside is that we will lose the option to set a custom timeout
for overflow, but than can be added (if needed) as part of debugfs.

p80211item_pstr6_t is the size of "msg1.bssid" (16 bytes) but
msg1.bssid.data is type p80211pstr6_t and it is smaller (7 bytes). We
had just set that memory to zeroes earlier and now we're writing over it
with 0xff because we're writing past the end of the struct.
I don't know if this actually causes a problem. It may be that we
initialize the extra 0xff bytes correctly later. But the current code
is obviously wrong and we should fix it.

Commit 9256a47 fixed a deadlock condition, being sure that the buddy
list spinlock is always taken before the page spinlock.
However in zbud_free_and_delist() locking order is the opposite
(page lock -> list lock).
Possible unsafe locking scenario (reported by lockdep):
CPU0 CPU1
---- ----
lock(&(&zbpg->lock)->rlock);
lock(zbud_budlists_spinlock);
lock(&(&zbpg->lock)->rlock);
lock(zbud_budlists_spinlock);
Fix by grabbing the locks in opposite order in zbud_free_and_delist().

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd. For calling from outside interrupts, netif_rx_ni exists.
This stops the error "NOHZ: local_softirq_panding 08" that happens on
some machines with NOHZ and plip --- it is caused by the fact that
softirq is pending and ksoftirqd is sleeping.

Ramster can't be a module (yet) and depends on CONFIGFS_FS=y, but
allmodconfig builds with CONFIGFS_FS=m, which breaks the build.
And forcing CONFIGFS_FS=y with select breaks the build in other ways.
So just don't build ramster unless CONFIGFS_FS=y.
Also, while we're here, add a comment as to why BROKEN is depended.

In drivers/staging/rtl8192e/rtllib_softmac.c::rtllib_rx_assoc_resp()
we allocate memory for 'network' with kzalloc() and then proceed to
zero the already zeroed mem we got from kzalloc() with
memset(). That's redundant, so remove the memset()
We also fail to kfree() the memory we allocated for 'network' if we do not enter
if (ieee->current_network.qos_data.supported == 1) {
and the variable then goes out of scope.
To fix that I simply moved the kfree() that was inside that 'if'
statement to instead be just after it. It then covers both the case
where we take the branch and when we don't.

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.
This patch adds new files necessary for ramster support: The file
ramster.h declares externs and some pampd bitfield manipulation. The
file zcache.h declares some zcache functions that now must be accessed
from the ramster glue code. The file r2net.c is the glue between zcache
and the messaging layer, providing routines called from zcache that
initiate messages, and routines that handle messages by calling zcache.
TODO explains future plans for merging.

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.
This patch incorporates changes transforming zcache to work with
a remote store.
In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle
incoming data resulting from an async get) routines combine with a handful
of changes to existing pamops interfaces allow the generic tmem code
to support asynchronous operations. Also, a new tmem_xhandle struct
groups together key information that must be passed to remote tmem stores.
Zcache-main.c is augmented with a large amount of ramster-specific code
to handle remote operations and "foreign" pages on both ends of the
"remotify" protocol. New "foreign" pools are auto-created on demand.
A "selfshrinker" thread periodically repatriates remote persistent pages
when local memory conditions allow. For certain operations, a queue is
necessary to guarantee strict ordering as out-of-order puts/flushes can
cause strange race conditions. Pampd pointers now either point to local
memory OR describe a remote page; to allow the same 64-bits to describe
either, the LSB is used to differentiate. Some acrobatics must be performed
to ensure local memory is available to handle a remote persistent get,
or deal with the data directly anyway if the malloc failed. Lots
of ramster-specific statistics are available via sysfs.
Note: Some debug ifdefs left in for now.

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.
Zcache is in the process of converting allocators, from xvmalloc to zsmalloc.
Further, RAMster V5 testing to date has been done only with xvmalloc.
To avoid merging problems, a linux-3.2 copy of xvmalloc is incorporated by
this patch. Later patches will be able to eliminate xvmalloc and use zsmalloc.

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.
This patch copies files from drivers/staging/zcache. RAMster compresses
pages locally before transmitting them to another node, so we can
leverage the zcache and tmem code directly. Note: there are
no ramster-specific changes yet to these files.
(Why copy? The ramster tmem.c/tmem.h changes are definitely shareable
between zcache and ramster; the eventual destination for tmem.c
is the linux lib directory. Ramster changes to zcache are more substantial
and zcache is currently undergoing some significant unrelated changes
(including a new allocator and breaking zcache-main.c into smaller files),
so it seemed best to branch temporarily and merge later.)

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.
This patch provides the cluster and messaging foundation for RAMster,
implementing the basic cluster discovery, mapping, heartbeat / keepalive,
and messaging ("r2net") that RAMster requires for internode communication.
This code heavily leverages code from the ocfs2 cluster layer but
has been extended, interfaces to userland changed, and external functions
renamed so that RAMster and ocfs2 can co-exist in the kernel and userland.
