Add driver support for the Texas Instruments BQ24190 battery charger.
Some of the information provided by the device is about the charger and
other information is about the battery so create two power_supply objects
(one for each) and provide the appropriate information for each one.
The device has many fields that go beyond what is reasonable to report or
modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver
exports the register fields via sysfs. They are prefixed by 'f_' (for
'field') to make it easier to distinguish between a register field and a
"normal" sysfs file exported by the power_supply infrastructure.

On a high-traffic router with many processors and many IPv6 dst
entries, soft lockup in fib6_run_gc() can occur when number of
entries reaches gc_thresh.
This happens because fib6_run_gc() uses fib6_gc_lock to allow
only one thread to run the garbage collector but ip6_dst_gc()
doesn't update net->ipv6.ip6_rt_last_gc until fib6_run_gc()
returns. On a system with many entries, this can take some time
so that in the meantime, other threads pass the tests in
ip6_dst_gc() (ip6_rt_last_gc is still not updated) and wait for
the lock. They then have to run the garbage collector one after
another which blocks them for quite long.
Resolve this by replacing special value ~0UL of expire parameter
to fib6_run_gc() by explicit "force" parameter to choose between
spin_lock_bh() and spin_trylock_bh() and call fib6_run_gc() with
force=false if gc_thresh is reached but not max_size.

vmpressure is called synchronously from reclaim where the target_memcg
is guaranteed to be alive but the eventfd is signaled from the work
queue context. This means that memcg (along with vmpressure structure
which is embedded into it) might go away while the work item is pending
which would result in use-after-release bug.
We have two possible ways how to fix this. Either vmpressure pins memcg
before it schedules vmpr->work and unpin it in vmpressure_work_fn or
explicitely flush the work item from the css_offline context (as
suggested by Tejun).
This patch implements the later one and it introduces vmpressure_cleanup
which flushes the vmpressure work queue item item. It hooks into
mem_cgroup_css_offline after the memcg itself is cleaned up.

Introduce enbale_hca and disable_hca commands to signify when the
driver starts or ceases to operate on the device.
In addition the driver will use boot and init pages count; boot pages
is required to allow firmware to complete boot commands and the other
to complete init hca. Command interface revision is bumped to 4 to
enforce using supported firmware.
This patch breaks compatibility with old versions of firmware (< 4);
however, the first GA firmware we will publish will support version 4
so this should not be a problem.

Calling freeze_processes sets a global flag that will cause any
process that calls try_to_freeze to enter the refrigerator. It
skips sending a signal to the current task, but if the current
task ever hits try_to_freeze, all threads will be frozen and the
system will deadlock.
Set a new flag, PF_SUSPEND_TASK, on the task that calls
freeze_processes. The flag notifies the freezer that the thread
is involved in suspend and should not be frozen. Also add a
WARN_ON in thaw_processes if the caller does not have the
PF_SUSPEND_TASK flag set to catch if a different task calls
thaw_processes than the one that called freeze_processes, leaving
a task with PF_SUSPEND_TASK permanently set on it.
Threads that spawn off a task with PF_SUSPEND_TASK set (which
swsusp does) will also have PF_SUSPEND_TASK set, preventing them
from freezing while they are helping with suspend, but they need
to be dead by the time suspend is triggered, otherwise they may
run when userspace is expected to be frozen. Add a WARN_ON in
thaw_processes if more than one thread has the PF_SUSPEND_TASK
flag set.

Commit 18d627113b (firewire: prevent dropping of completed iso packet
header data) was intended to be an obvious bug fix, but libdc1394 and
FlyCap2 depend on the old behaviour by ignoring all returned information
and thus not noticing that not all packets have been received yet. The
result was that the video frame buffers would be saved before they
contained the correct data.
Reintroduce the old behaviour for old clients.

- Davinci and nomadik updates due to new code merged this merge window
- Fixes for UART on Samsung platforms, both PM and clock-related

The most critical one is a fix for ahci oops during boot. Also, a new

seems rather common on the device and it's unlikely to get any love in

think we'd probably be better of making the driver depend on BROKEN in
a couple releases"

We attempted to address a regression introduced by commit a57f7f9
(ACPICA: Add Windows8/Server2012 string for _OSI method.) after which
ACPI video backlight support doesn't work on a number of systems,
because the relevant AML methods in the ACPI tables in their BIOSes
become useless after the BIOS has been told that the OS is compatible
with Windows 8. That problem is tracked by the bug entry at:
https://bugzilla.kernel.org/show_bug.cgi?id=51231
Commit 8c5bd7a (ACPI / video / i915: No ACPI backlight if firmware
expects Windows 8) introduced for this purpose essentially prevented
the ACPI backlight support from being used if the BIOS had been told
that the OS was compatible with Windows 8 and the i915 driver was
loaded, in which case the backlight would always be handled by i915.
Unfortunately, however, that turned out to cause problems with
backlight to appear on multiple systems with symptoms indicating that
i915 was unable to control the backlight on those systems as
expected.
For this reason, revert commit 8c5bd7a, but leave the function
acpi_video_backlight_quirks() introduced by it, because another
commit on top of it uses that function.

"This contains two patches, both of which aren't fixes per-se but I

One removes bcache_subsys_id which was added without proper review

unconditionally disabled, so this was never exposed to userland. The
cgroup subsys_id is removed. Kent will remove the affected (disabled)
code through bcache branch.
The other simplifies task_group_path_from_hierarchy(). The function
doesn't currently have in-kernel users but there are external code and
development going on dependent on the function and making the function
available for 3.11 would make things go smoother"

The em_x270_mci_setpower() and em_x270_usb_hub_init() functions
call regulator_enable(), which may return an error that must

This changes the em_x270_usb_hub_init() function to bail out
if it fails, and changes the pxamci_platform_data->setpower
callback so that the a failed em_x270_mci_setpower call
can be propagated by the pxamci driver into the mmc core.

Pull ACPI video support fixes from Rafael Wysocki:
"I'm sending a separate pull request for this as it may be somewhat
controversial. The breakage addressed here is not really new and the
fixes may not satisfy all users of the affected systems, but we've had
so much back and forth dance in this area over the last several weeks
that I think it's time to actually make some progress.
The source of the problem is that about a year ago we started to tell
BIOSes that we're compatible with Windows 8, which we really need to
do, because some systems shipping with Windows 8 are tested with it
and nothing else, so if we tell their BIOSes that we aren't compatible
with Windows 8, we expose our users to untested BIOS/AML code paths.
However, as it turns out, some Windows 8-specific AML code paths are
not tested either, because Windows 8 actually doesn't use the ACPI
methods containing them, so if we declare Windows 8 compatibility and
attempt to use those ACPI methods, things break. That occurs mostly
in the backlight support area where in particular the _BCM and _BQC
methods are plain unusable on some systems if the OS declares Windows
8 compatibility.
[ The additional twist is that they actually become usable if the OS
says it is not compatible with Windows 8, but that may cause
problems to show up elsewhere ]
Investigation carried out by Matthew Garrett indicates that what
Windows 8 does about backlight is to leave backlight control up to
individual graphics drivers. At least there's evidence that it does
that if the Intel graphics driver is used, so we've decided to follow
Windows 8 in that respect and allow i915 to control backlight (Daniel
likes that part).
The first commit from Aaron Lu makes ACPICA export the variable from
which we can infer whether or not the BIOS believes that we are
compatible with Windows 8.
The second commit from Matthew Garrett prepares the ACPI video driver
by making it initialize the ACPI backlight even if it is not going to
be used afterward (that is needed for backlight control to work on
Thinkpads).
The third commit implements the actual workaround making i915 take
over backlight control if the firmware thinks it's dealing with
Windows 8 and is based on the work of multiple developers, including
Matthew Garrett, Chun-Yi Lee, Seth Forshee, and Aaron Lu.
The final commit from Aaron Lu makes us follow Windows 8 by informing
the firmware through the _DOS method that it should not carry out
automatic brightness changes, so that brightness can be controlled by
GUI.
Hopefully, this approach will allow us to avoid using blacklists of
systems that should not declare Windows 8 compatibility just to avoid
backlight control problems in the future.

Here are a few iio driver fixes for 3.11-rc2. They are still spread
across drivers/iio and drivers/staging/iio so they are coming in through
this tree.
I've also removed the drivers/staging/csr/ driver as the developers who
originally sent it to me have moved on to other companies, and CSR still
will not send us the specs for the device, making the driver pretty much
obsolete and impossible to fix up. Deleting it now prevents people from
sending in lots of tiny codingsyle fixes that will never go anywhere.
It also helps to offset the large lustre filesystem merge that happened
in 3.11-rc1 in the overall 3.11.0 diffstat. :)

2) Get rid of a stupid reimplementation on "%*phC" in our sysfs MAC

attempt to perform early socket demux, just like ipv6 does. From
Eric Dumazet.
7) Add missing locking on vxlan device removal, from Stephen
Hemminger.
8) xen-netfront has to make two passes over an SKB to prepare it for
transfer. One pass calculates the number of slots needed, the
second massages the SKB and fills the slots. Unfortunately, the
first pass doesn't calculate the number of slots properly so we
can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
work out so well. Fix from Jan Beulich with help and discussion
with several others.
9) Fix a similar problem in tun and macvtap, which have to split up
scatter-gather elements at PAGE_SIZE boundaries. Don't do
zerocopy if it would result in a > MAX_SKB_FRAGS skb. Fixes from
Jason Wang.
10) On receive, once we've decoded the VLAN state completely, clear

The ARM OABI and EABI disagree on the alignment of structures
with small members, so module init tools may interpret the
ssb device table incorrectly, as shown by this warning when
building the b43 device driver in an OABI kernel:
FATAL: drivers/net/wireless/b43/b43: sizeof(struct ssb_device_id)=6 is
not a modulo of the size of section __mod_ssb_device_table=88.
Forcing the default (EABI) alignment on the structure makes this
problem go away. Since the ssb_device_id may have the same problem,
better fix both structures.
