649b3b8c4e r8169: fix driver shutdown WoL regression.
Due to commit 92fc43b415 ("r8169: modify the
flow of the hw reset."), rtl8169_hw_reset stomps during driver shutdown on
RxConfig bits which are needed for WOL on some versions of the hardware.

As these bits were formerly set from the r81{0x, 68}_pll_power_down methods,
factor them out for use in the driver shutdown (rtl_shutdown) handler.

I favored __rtl8169_get_wol() -hardware state indication- over
RTL_FEATURE_WOL as the latter has become a good candidate for removal.

4d97480b18 bonding: use local function pointer of bond->recv_probe in bond_handle_frame
The bond->recv_probe is called in bond_handle_frame() when
a packet is received, but bond_close() sets it to NULL. So,
a panic occurs when both functions work in parallel.

Why this happen:
After null pointer check of bond->recv_probe, an sk_buff is
duplicated and bond->recv_probe is called in bond_handle_frame.
So, a panic occurs when bond_close() is called between the
check and call of bond->recv_probe.

Patch:
This patch uses a local function pointer of bond->recv_probe
in bond_handle_frame(). So, it can avoid the null pointer
dereference.

6230c9b4f8 bluetooth: Properly clone LSM attributes to newly created child connections
The Bluetooth stack has internal connection handlers for all of the various
Bluetooth protocols, and unfortunately, they are currently lacking the LSM
hooks found in the core network stack's connection handlers.  I say
unfortunately, because this can cause problems for users who have have an
LSM enabled and are using certain Bluetooth devices.  See one problem
report below:

 * http://bugzilla.redhat.com/show_bug.cgi?id=741703

In order to keep things simple at this point in time, this patch fixes the
problem by cloning the parent socket's LSM attributes to the newly created
child socket.  If we decide we need a more elaborate LSM marking mechanism
for Bluetooth (I somewhat doubt this) we can always revisit this decision
in the future.

bcd5cff721 cputimer: Cure lock inversion
There's a lock inversion between the cputimer->lock and rq->lock;
notably the two callchains involved are:

 update_rlimit_cpu()
   sighand->siglock
   set_process_cpu_timer()
     cpu_timer_sample_group()
       thread_group_cputimer()
         cputimer->lock
         thread_group_cputime()
           task_sched_runtime()
             ->pi_lock
             rq->lock

 scheduler_tick()
   rq->lock
   task_tick_fair()
     update_curr()
       account_group_exec()
         cputimer->lock

Where the first one is enabling a CLOCK_PROCESS_CPUTIME_ID timer, and
the second one is keeping up-to-date.

This problem was introduced by e8abccb719 ("posix-cpu-timers: Cure
SMP accounting oddities").

Cure the problem by removing the cputimer->lock and rq->lock nesting,
this leaves concurrent enablers doing duplicate work, but the time
wasted should be on the same order otherwise wasted spinning on the
lock and the greater-than assignment filter should ensure we preserve
monotonicity.

f36c23bb9f udplite: fast-path computation of checksum coverage
Commit 903ab86d19 of 1 March this year ("udp: Add
lockless transmit path") introduced a new fast TX path that broke the checksum
coverage computation of UDP-lite, which so far depended on up->len (only set
if the socket is locked and 0 in the fast path).

Fixed by providing both fast- and slow-path computation of checksum coverage.
The latter can be removed when UDP(-lite)v6 also uses a lockless transmit path.

a84a79e4d3 Avoid using variable-length arrays in kernel/sys.c
The size is always valid, but variable-length arrays generate worse code
for no good reason (unless the function happens to be inlined and the
compiler sees the length for the simple constant it is).

Also, there seems to be some code generation problem on POWER, where
Henrik Bakken reports that register r28 can get corrupted under some
subtle circumstances (interrupt happening at the wrong time?).  That all
indicates some seriously broken compiler issues, but since variable
length arrays are bad regardless, there's little point in trying to
chase it down.

"Just don't do that, then".

1: If you use a facility then #include the file that defines/declares
   that facility.  Don't depend on other header files pulling in ones

Otherwise, we may run into some compiling error like the following one,
if any file includes localtimer.h without CONFIG_LOCAL_TIMERS defined.

  arch/arm/include/asm/localtimer.h: In function ‘local_timer_setup’:

29a541f6c1 ARM: 7117/1: perf: fix HW_CACHE_* events on Cortex-A9
Using COHERENT_LINE_{MISS,HIT} for cache misses and references
respectively is completely wrong. Instead, use the L1D events which
are a better and more useful approximation despite ignoring instruction
traffic.

c0771df8d5 intel-iommu: Export a flag indicating that the IOMMU is used for iGFX.
We really don't want this to work in the general case; device drivers
*shouldn't* care whether they are behind an IOMMU or not. But the
integrated graphics is a special case, because the IOMMU and the GTT are
all kind of smashed into one and generally horrifically buggy, so it's
reasonable for the graphics driver to want to know when the IOMMU is
active for the graphics hardware.

6fbcfb3e46 intel-iommu: Workaround IOTLB hang on Ironlake GPU
To work around a hardware issue, we have to submit IOTLB flushes while
the graphics engine is idle. The graphics driver will (we hope) go to
great lengths to ensure that it gets that right on the affected
chipset(s)... so let's not screw it over by deferring the unmap and
doing it later. That wouldn't be very helpful.

153b19a3b9 x86, mrst: use a temporary variable for SFI irq
SFI tables reside in RAM and should not be modified once they are
written.  Current code went to set pentry->irq to zero which causes
subsequent reads to fail with invalid SFI table checksum.  This will
break kexec as the second kernel fails to validate SFI tables.

To fix this we use temporary variable for irq number.

bf164c58e5 hwmon: (w83627ehf) Properly report thermal diode sensors
The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".

Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.

gpio_base was set to 0 if no system platform data or open firmware
platform data was provided. This led to conflicts, if any other gpiochip
with a gpiobase of 0 was instantiated already. Setting it to -1 will
automatically use the first one available.
