Pull networkign fixes from David Miller:
"Networking bug fixes, Cacio e Pepe edition:
1) BNX2X accidently accesses chip rev specific registers without an
appropriate guard, fix from Ariel Elior.
2) When we removed the routing cache, we set ip_rt_max_size to ~0 just
to keep reporting a value to userspace via sysfs. But the ipv4
IPSEC layer was using this to tune itself which is completely bogus
to now do. Fix from Steffen Klassert.
3) Missing initialization in netfilter ipset code from Jozsef
Kadlecsik.
4) Check CTA_TIMEOUT_NAME length properly in netfilter cttimeout code,
fix from Florian Westphal.
5) After removing the routing cache, we inadvertantly are caching
multicast routes that end up looping back locally, we cannot do
that legitimately any more. Fix from Julian Anastasov.

dev_pm_qos_add_request() can return 0, 1, or a negative error code,
therefore the correct error test is "if (error < 0)." Checking just for
non-zero return code leads to erroneous setting of the req->dev pointer
to NULL, which then leads to a repeated call to
dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
leads to an Oops, when the I2C host adapter is unloaded and reloaded again
because of the inconsistent state of its QoS request list.

To allow debuggers to unwind through signal frames, we create a fake
stack unwinding prologue containing the link register and frame pointer
of the interrupted context. The signal frame is then offset by 16 bytes
to make room for the two saved registers which are pushed onto the frame
of the *interrupted* context, rather than placed directly above the
signal stack.
This doesn't work when an alternative signal stack is set up for a SEGV
handler, which is raised in response to RLIMIT_STACK being reached. In
this case, we try to push the unwinding prologue onto the full stack and
subsequently take a fault which we fail to resolve, causing setup_return
to return -EFAULT and handle_signal to force_sigsegv on the current task.
This patch fixes the problem by including the unwinding prologue as part
of the rt_sigframe definition, which is populated during setup_sigframe,
ensuring that it always ends up on the signal stack.

A recent patch changed some irq routines from inlines to functions.
These routines are called by the tracer code. Now that they're functions,
if they are compiled for function tracing they will call the tracer
and crash the system due to infinite recursion. The fix disables
tracing in these functions by using "notrace" in the function
definition.

013bf490-0149e01f : Kernel data

but the two System RAM ranges should be one single range. This particular
case will result in kexec failure on Octeon systems if the kernel being
loaded by kexec is bigger than the already running kernel.

Commit 09e05d48 introduced a wait for transaction commit into
journal_unmap_buffer() in the case we are truncating a buffer undergoing commit
in the page stradding i_size on a filesystem with blocksize < pagesize. Sadly
we forgot to drop buffer lock before waiting for transaction commit and thus
deadlock is possible when kjournald wants to lock the buffer.
Fix the problem by dropping the buffer lock before waiting for transaction
commit. Since we are still holding page lock (and that is OK), buffer cannot
disappear under us.

After we've done __elv_add_request() and __blk_run_queue() in
blk_execute_rq_nowait(), the request might finish and be freed
immediately. Therefore checking if the type is REQ_TYPE_PM_RESUME
isn't safe afterwards, because if it isn't, rq might be gone.
Instead, check beforehand and stash the result in a temporary.
This fixes crashes in blk_execute_rq_nowait() I get occasionally when
running with lots of memory debugging options enabled -- I think this
race is usually harmless because the window for rq to be reallocated
is so small.

Calling the request handler directly on a plugged queue defeats
the performance improvements provided by the plugging mechanism.
Use the __blk_run_queue function instead of calling the request
handler directly, so that we don't interfere with the block

Request based dm attempts to re-run the request queue off the
request completion path. If used with a driver that potentially does
end_io from its request_fn, we could deadlock trying to recurse
back into request dispatch. Fix this by punting the request queue

Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities. This is useful for the C
decompressor implementations used for unpacking compressed kernels.
This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.
The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.
For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

hrtimer_start was added in 198fd638 and ae515197. The patch below tries
to use RCU_NONIDLE around it to avoid the above report.

The LEN variable is unsigned, therefore checking whether it is less than 0 is
useless. Also drop the LEN variable, since the COUNT parameter can be used
instead.

Starting from 3.6 we cache output routes for
multicasts only when using route to 224/4. For local receivers
we can set RTCF_LOCAL flag depending on the membership but
in such case we use maddr and saddr which are not caching
keys as before. Additionally, we can not use same place to
cache routes that differ in RTCF_LOCAL flag value.
Fix it by caching only RTCF_MULTICAST entries
without RTCF_LOCAL (send-only, no loopback). As a side effect,
we avoid unneeded lookup for fnhe when not caching because
multicasts are not redirected and they do not learn PMTU.
Thanks to Maxime Bizon for showing the caching
problems in __mkroute_output for 3.6 kernels: different
RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or
ip_output call and the visible problem is that traffic can
not reach local receivers via loopback.

commit 500a8cc466a24e2fbc4c86ef9c6467ae2ffdeb0c

drm/i915: parse eDP panel color depth from VBT block
originally introduced parsing bpp for eDP from VBT, with a default of 18
bpp if the eDP BIOS data block is not present. Turns out that default seems
to break the Macbook Pro with retina display, as noted in
commit 4344b813f105a19f793f1fd93ad775b784648b95

drm/i915: ignore eDP bpc settings from vbt
Since we can't ignore bpc settings from VBT completely after all, get rid
of the default. Do not clamp eDP to 18 bpp by default if the eDP BDB is
missing from VBT.
