Pull sound updates from Takashi Iwai:
"This contains pretty many small commits covering fairly large range of
files in sound/ directory. Partly because of additional API support
and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support
of D3 clock-stop. Also changing the power_save option in sysfs
kicks off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in
HD-audio are continued cleanups and standardization for the generic
auto parser and bug fixes (HBR, device-specific fixups), in
addition to the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.
- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers
- A new driver for DA9055 and the support for regulator bypass mode."

exec: make de_thread() killable
Change de_thread() to use KILLABLE rather than UNINTERRUPTIBLE while
waiting for other threads. The only complication is that we should
clear ->group_exit_task and ->notify_count before we return, and we
should do this under tasklist_lock. -EAGAIN is used to match the
initial signal_group_exit() check/return, it doesn't really matter.
This fixes the (unlikely) race with coredump. de_thread() checks
signal_group_exit() before it starts to kill the subthreads, but this
can't help if another CLONE_VM (but non CLONE_THREAD) task starts the
coredumping after de_thread() unlocks ->siglock. In this case the
killed sub-thread can block in exit_mm() waiting for coredump_finish(),
execing thread waits for that sub-thead, and the coredumping thread
waits for execing thread. Deadlock.

The returned route can be cached as follows:
- in NH exception: because the cached routes are not shared

- in FIB NH: when using gateway because all destinations for
NH share same gateway

should not cache the RTCF_DOREDIRECT flag in nh_rth_input because
the same fib_info can be used for traffic that is not redirected,
eg. from other input devices or from sources that are not in same subnet.
As result, we have to disable the caching of RTCF_DOREDIRECT
flag and to force source validation for the case when forwarding
traffic to the input device. If traffic comes from directly connected
source we allow redirection as it was done before both changes.
Avoid setting RTCF_DOREDIRECT if IN_DEV_TX_REDIRECTS
is disabled, this can avoid source address validation and to
help caching the routes.

vlan: don't deliver frames for unknown vlans to protocols
6a32e4f9dd9219261f8856f817e6655114cfec2f made the vlan code skip marking
vlan-tagged frames for not locally configured vlans as PACKET_OTHERHOST if
there was an rx_handler, as the rx_handler could cause the frame to be received
on a different (virtual) vlan-capable interface where that vlan might be
configured.
As rx_handlers do not necessarily return RX_HANDLER_ANOTHER, this could cause
frames for unknown vlans to be delivered to the protocol stack as if they had
been received untagged.
For example, if an ipv6 router advertisement that's tagged for a locally not
configured vlan is received on an interface with macvlan interfaces attached,
macvlan's rx_handler returns RX_HANDLER_PASS after delivering the frame to the
macvlan interfaces, which caused it to be passed to the protocol stack, leading
to ipv6 addresses for the announced prefix being configured even though those
are completely unusable on the underlying interface.
The fix moves marking as PACKET_OTHERHOST after the rx_handler so the
rx_handler, if there is one, sees the frame unchanged, but afterwards,
before the frame is delivered to the protocol stack, it gets marked whether
there is an rx_handler or not.

Pull UBI fastmap changes from Artem Bityutskiy:
"This pull request contains the UBI fastmap support implemented by
Richard Weinberger from Linutronix. Fastmap is designed to address
UBI's slow scanning issues. Namely, it introduces a new on-flash
data-structure called "fastmap", which stores the information about
logical<->physical eraseblocks mappings. So now to get this
information just read the fastmap, instead of doing full scan. More
information here can be found in Richard's announcement in LKML
(Subject: UBI: Fastmap request for inclusion (v19)):
One thing I want to explicitly say is that fastmap did not have large
enough linux-next exposure. It is partially my fault - I did not
respond quickly enough. I _really_ apologize for this. But it had
good testing and disabled by default, so I do not expect that we'll
break anything.
Fastmap is declared as experimental so far, and it is off by default.
We did declare that the on-flash format may be changed. The reason
for this is that no one used it in real production so far, so there is
a high risk that something is missing. Besides, we do not have
user-space tools supporting fastmap so far.
Nevertheless, I suggest we merge this feature. Many people want UBI's
scanning bottleneck to be fixed and merging fastmap now should
accelerate its production use. The plan is to make it bullet-prove,
somewhat clean-up, and make it the default for UBI. I do not know how
many kernel releases will it take.
Basically, I what I want to do for fastmap is something like Linus did
for btrfs few years ago."

net: gro: fix a potential crash in skb_gro_reset_offset
Before accessing skb first fragment, better make sure there
is one.
This is probably not needed for old kernels, since an ethernet frame
cannot contain only an ethernet header, but the recent GRO addition
to tunnels makes this patch needed.
Also skb_gro_reset_offset() can be static, it actually allows
compiler to inline it.

The retry loop in neigh_resolve_output() and neigh_connected_output()

The function dmfe_init_one() return 0 for success and negative value
for most of its internal tests failures. There are three exceptions
that are error cases going to err_out_*:. Fore this three cases the
function abort its success execution path, but returns non negative
value, making it dificult for a caller function to notice the error.
This patch fixes the error cases that do not return negative values.
This was found by Coccinelle, but the code change was made by hand.
This patch is not robot generated.
A simplified version of the semantic match that finds this problem is
as follows: (http://coccinelle.lip6.fr/)

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"This is the first chunk of ARM updates for this merge window.
Conflicts are expected in two files - asm/timex.h and
mach-integrator/integrator_cp.c. Nothing particularly stands out more
than anything else.
Most of the growth is down to the opcodes stuff from Dave Martin,
which is countered by Rob's patches to use more of the asm-generic
headers on ARM."
(A few more conflicts grew since then, but it all looked fairly trivial)
