w1_bq27000 adds a bq27000-battery platform device but does not provide
platform data for it. This causes the bq27x00 driver to dereference a NULL
pointer.
So provide the appropriate platform data. This requires modifying
w1_bq27000_read so that it find the w1 device as the parent of the bq device.
Also there is no point exporting w1_bq27000_read as nothing else uses it
or could use it. So make it static.
Finally, as there is no way to track how many batteries have been found, and
we will probably only find one, use an id number of '-1' to assert that this
is a unique instance.

not all platforms will use all of those ehci_*
symbols on their hc_driver structure. Sometimes
we might need to provide a modified version of
a certain method or not provide it at all, as is
the case with OMAPs which don't support port handoff
feature.
Whenever we compile a kernel for an OMAP board with
EHCI enabled, we get compile warnings:
drivers/usb/host/ehci-hub.c:1079: warning: 'ehci_relinquish_port' \
defined but not used
drivers/usb/host/ehci-hub.c:1088: warning: 'ehci_port_handed_over' \
defined but not used
In order to cleanup those warnings, we're adding
__maybe_unused annotation to those functions.

For files that include asm/processor.h but not asm/system.h:
arch/arm/mach-msm/include/mach/uncompress.h: In function 'putc':
arch/arm/mach-msm/include/mach/uncompress.h:48:3: error: implicit declaration of function 'smp_mb' [-Werror=implicit-function-declaration]
In this case, smp_mb() is from the cpu_relax() call in the msm putc().
It likely went uncaught when the uncompress.h change went in since the
defconfig didn't enable that code path, but later changes (e76f4750f4:
ARM: debug: arrange Kconfig options more logically) resulted in the
option being on for msm_defconfig and thus exposed it.

Bootup with lockdep enabled has been broken on v7 since b46c0f74657d
("ARM: 7321/1: cache-v7: Disable preemption when reading CCSIDR").
This is because v7_setup (which is called very early during boot) calls
v7_flush_dcache_all, and the save_and_disable_irqs added by that patch
ends up attempting to call into lockdep C code (trace_hardirqs_off())
when we are in no position to execute it (no stack, MMU off).
Fix this by using a notrace variant of save_and_disable_irqs. The code
already uses the notrace variant of restore_irqs.

This patch moves the MAC HW initialization and
the HW feature verification from the open to the probe
function as D. Miller suggested.
So the patch actually reorganizes and tidies-up some parts of

Appropriate flag is set using security information provided in
connect request. mwifiex_is_network_compatible() routine uses them
to check if driver's setting is compatible with AP. Association is

For some corner cases, it is observed that association is failed

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.

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.)

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.

Currently registers with a value of 0 are ignored when initializing the register
defaults from raw defaults. This worked in the past, because registers without a
explicit default were assumed to have a default value of 0. This was changed in
commit b03622a8 ("regmap: Ensure rbtree syncs registers set to zero properly").
As a result registers, which have a raw default value of 0 are now assumed to
have no default. This again can result in unnecessary writes when syncing the
cache. It will also result in unnecessary reads for e.g. the first update
operation. In the case where readback is not possible this will even let the
update operation fail, if the register has not been written to before.
So this patch removes the check. Instead it adds a check to ignore raw defaults
for registers which are volatile, since those registers are not cached.

The check for save_init_fpu() (introduced in commit 5b1cbac37798: "i387:
make irq_fpu_usable() tests more robust") was the wrong way around, but
I hadn't noticed, because my "tests" were bogus: the FPU exceptions are
disabled by default, so even doing a divide by zero never actually
triggers this code at all unless you do extra work to enable them.
So if anybody did enable them, they'd get one spurious warning.

We encountered an issue that was easily observable on s/390 systems but
could really happen anywhere. The timing just seemed to hit reliably
on s/390 with limited memory.
The gist is that when an unexpected set_page_dirty() happened, we'd
run into the BUG() in btrfs_writepage_fixup_worker since it wasn't
properly set up for delalloc.
This patch does the following:
- Performs the missing delalloc in the fixup worker
- Allow the start hook to return -EBUSY which informs __extent_writepage
that it should mark the page skipped and not to redirty it. This is
required since the fixup worker can fail with -ENOSPC and the page
will have already been redirtied. That causes an Oops in
drop_outstanding_extents later. Retrying the fixup worker could
lead to an infinite loop. Deferring the page redirty also saves us
some cycles since the page would be stuck in a resubmit-redirty loop
until the fixup worker completes. It's not harmful, just wasteful.
- If the fixup worker fails, we mark the page and mapping as errored,
and end the writeback, similar to what we would do had the page
actually been submitted to writeback.

$ mkfs.btrfs disk2
$ mount disk1 /mnt
$ fstrim -v /mnt
$ btrfs device add disk2 /mnt
$ btrfs device del disk1 /mnt
$ fstrim -v /mnt
This is because after we delete the device, the block group may start from

idle_cpu() is called on irq entry to guess if we need to call
tick_check_idle(). This way we can catch up with jiffies if the tick
was stopped, stop accounting idle time during the interrupt and
maintain the sched clock if it is unstable.
But if we are going to exit the idle loop to schedule a new task (ie:
if we have a task in the runqueue or a remotely enqueued ttwu to
perform), the idle_cpu() check will return 0 such that we miss the
call to tick_check_idle() for all interrupts happening before we
schedule the new task.
As a result these interrupts and the softirqs coming along may deal
with stale jiffies values, bad sched clock values, and won't substract
their time from the idle time accounting.
Fix this with using is_idle_task() instead that strictly checks that
we are running the idle task, without caring about the fact we are
going to schedule a task soon.

ts->inidle is set by tick_nohz_idle_enter() and unset by
tick_nohz_idle_exit(). However these two calls are assumed
to be always paired. This means that by the time we call
tick_nohz_idle_exit(), ts->inidle is supposed to be always
set to 1.
Remove the checks for ts->inidle in tick_nohz_idle_exit().
This simplifies a bit the code and improves its debuggability
(ie: ensure the call is paired with a tick_nohz_idle_enter()
call).

Platforms with Always Running APIC Timer doesn't use the broadcast timer
but the kernel is leaving the broadcast timer (HPET in this case)
in oneshot mode.
On these platforms, before the switch to oneshot mode, broadcast device is
actually in shutdown mode. Code checks for empty tick_broadcast_mask and
avoids going into the periodic mode.
During switch to oneshot mode, add the same tick_broadcast_mask checks in the
tick_broadcast_switch_to_oneshot() and avoid the broadcast device going into
the oneshot mode.
