Included fixes are:
- update the client entry status flags when using the "early client
detection". This makes the Distributed AP isolation correctly work;
- transfer the client entry status flags when recovering the translation
table from another node. This makes the Distributed AP isolation correctly
work;
- prevent the "early client detection mechanism" to add clients belonging to
other backbone nodes in the same LAN. This breaks connectivity when using this
mechanism together with the Bridge Loop Avoidance
- process broadcast packets with the Bridge Loop Avoidance before any other
component. BLA can possibly drop the packets based on the source address. This
makes the "early client detection mechanism" correctly work when used with
BLA.

This is mostly a revert of 01dc52ebdf47 ("oom: remove deprecated oom_adj")
from Davidlohr Bueso.
It reintroduces /proc/pid/oom_adj for backwards compatibility with earlier
kernels. It simply scales the value linearly when /proc/pid/oom_score_adj
is written.
The major difference is that its scheduled removal is no longer included
in Documentation/feature-removal-schedule.txt. We do warn users with a
single printk, though, to suggest the more powerful and supported
/proc/pid/oom_score_adj interface.

Pull ARM SoC fixes from Olof Johansson:
"We've been sitting on this longer than we meant to due to travel and
other activities, but the number of patches is luckily not that high.
Biggest changes are from a batch of OMAP bugfixes, but there are a few
for the broader set of SoCs too (bcm2835, pxa, highbank, tegra, at91
and i.MX).
The OMAP patches contain some fixes for MUSB/PHY on omap4 which ends
up being a bit on the large side but needed for legacy (non-DT)
platforms. Beyond that there are a handful of hwmod/pm changes.
So, fairly noncontroversial stuff all in all, and as usual around this
time the fixes are well targeted at specific problems."

Currently, callback invocations from callback-free CPUs are accounted to
the CPU that registered the callback, but using the same field that is
used for normal callbacks. This makes it impossible to determine from
debugfs output whether callbacks are in fact being diverted. This commit
therefore adds a separate ->n_nocbs_invoked field in the rcu_data structure
in which diverted callback invocations are counted. RCU's debugfs tracing
still displays normal callback invocations using ci=, but displayed
diverted callbacks with nci=.

RCU callback execution can add significant OS jitter and also can
degrade both scheduling latency and, in asymmetric multiprocessors,
energy efficiency. This commit therefore adds the ability for selected
CPUs ("rcu_nocbs=" boot parameter) to have their callbacks offloaded
to kthreads. If the "rcu_nocb_poll" boot parameter is also specified,
these kthreads will do polling, removing the need for the offloaded
CPUs to do wakeups. At least one CPU must be doing normal callback
processing: currently CPU 0 cannot be selected as a no-CBs CPU.
In addition, attempts to offline the last normal-CBs CPU will fail.
This feature was inspired by Jim Houston's and Joe Korty's JRCU, and
this commit includes fixes to problems located by Fengguang Wu's
kbuild test robot.

This was always racy, but 268720903f87e0b84b161626c4447b81671b5d18
"uprobes: Rework register_for_each_vma() to make it O(n)" should be
blamed anyway, it made everything worse and I didn't notice.
register/unregister call build_map_info() and then do install/remove
breakpoint for every mm which mmaps inode/offset. This can obviously
race with fork()->dup_mmap() in between and we can miss the child.
uprobe_register() could be easily fixed but unregister is much worse,
the new mm inherits "int3" from parent and there is no way to detect
this if uprobe goes away.
So this patch simply adds percpu_down_read/up_read around dup_mmap(),
and percpu_down_write/up_write into register_for_each_vma().
This adds 2 new hooks into dup_mmap() but we can kill uprobe_dup_mmap()
and fold it into uprobe_end_dup_mmap().

The current mxs-auart driver is used for both mx23 and mx28.
But in mx23, the DMA has a bug(see errata:2836). We can not add the
DMA support in mx23, but we can add DMA support to auart in mx28.
So in order to add the DMA support for the auart in mx28, we should
distinguish the distinguish SOCs.
This patch adds a new platform_device_id table and a inline function
is_imx28_auart() to distinguish the mx23 and mx28.

Allows overriding default methods serial_in/serial_out.
In such platform specific replacement it is possible to use
other regshift, biased register offset, any other manipulation
that is not covered with common default methods.
Overriding default methods may be useful for platforms which got
serial peripheral with registers represented in big endian.
In this situation and assuming that 32 bit operations / alignment
is required then it may be useful to swab words before/after
accessing the serial registers.

_CRS_ info"
This reverts commit 0a290ac4252c85205cb924ff7f6da10cfd20fb01 on
the basis of the following comment from Bjorn Helgaas:
Here's my reasoning: this is a CheckPoint product, and it looks
like an appliance, not really a general-purpose machine. The issue
has apparently been there from day one, and the kernel shipped on
the machine complains noisily about the issue, but apparently
nobody bothered to investigate it.
This corruption will clearly break other ACPI-related things. We
can sort of work around this one (though the workaround does
prevent us from doing any PCI resource reassignment), but we have
no idea what the other lurking ACPI issues are (and we have no
assurance that *only* ACPI things are broken -- maybe the
memory corruption affects other unknown things). It may take
significant debugging effort to identify the next problem.
The only report I've seen (this one) is apparently from a
CheckPoint employee, so it's not clear that anybody else is trying
to run upstream Linux on it. Being a CheckPoint employee, [...]
is probably in a position to get the BIOS fixed.
You might still be able to convince me, but it seems like the
benefit to a quirk for this platform is small, and it does cost
everybody else something in code size and complexity.

The logic in the BLA mechanism may decide to drop broadcast packets
because the node may still be in the setup phase. For this reason,
further broadcast processing like the early client detection mechanism
must be done only after the BLA check.
This patches moves the invocation to BLA before any other broadcast
processing.

The "early client detection" mechanism must not add clients belonging
to other backbone nodes. Such clients must be reached by directly
using the LAN instead of the mesh.

When a TT response with the full table is sent, the client flags
should be sent as well. This patch fix the flags assignment when

Flags carried by a change_entry have to be always copied into the
client entry as they may contain important attributes (e.g.
TT_CLIENT_WIFI).
For instance, a client added by means of the "early detection
mechanism" has no flag set at the beginning, so they must be updated once the
proper ADD event is received.

This patch simply makes the tilegx net driver call request_irq with a
non-null name. It makes the output in /proc/interrupts more obvious, but
also helps tools that don't expect to find null there.

This will fix warnings like following when CONFIG_PM_SLEEP is not set:
warning: 'xxx_suspend' defined but not used [-Wunused-function]
warning: 'xxx_resume' defined but not used [-Wunused-function]
Because
SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn)
Only references the callbacks on CONFIG_PM_SLEEP (instead of CONFIG_PM).

ata_timing_find_mode could return NULL which is not checked by all
low-level ATA drivers using it and cause a NULL ptr deref. Warn at least
so that possible issues can get fixed easily.
