Pull media fixes from Mauro Carvalho Chehab:
- dvb core: there is a regression found when used with xine. For
whatever unknown reason, xine (and xine-lib clients) wants that the
frontend to tell what frequency he is using even before the PLL lock
(or at least, it expects a non-zero frequency).On DVB, the frequency is only actually known after a frequency
zig-zag seek, done by the DVB core. Anyway, the fix was trivial.
That solves Fedora BZ#808871.- ivtv: fix a regression when selecting the language channel

This merges the 32- and 64-bit versions of the x86 strncpy_from_user()
by just rewriting it in C rather than the ancient inline asm versions
that used lodsb/stosb and had been duplicated for (trivial) differences
between the 32-bit and 64-bit versions.While doing that, it also speeds them up by doing the accesses a word at
a time. Finally, the new routines also properly handle the case of
hitting the end of the address space, which we have never done correctly
before (fs/namei.c has a hack around it for that reason).Despite all these improvements, it actually removes more lines than it
adds, due to the de-duplication. Also, we no longer export (or define)
the legacy __strncpy_from_user() function (that was defined to not do
the user permission checks), since it's not actually used anywhere, and
the user address space checks are built in to the new code.Other architecture maintainers have been notified that the old hack in
fs/namei.c will be going away in the 3.5 merge window, in case they
copied the x86 approach of being a bit cavalier about the end of the
address space.Cc: linux-arch@vger.kernel.org

keyctl_session_to_parent(task) sets ->replacement_session_keyring,
it should be processed and cleared by key_replace_session_keyring().However, this task can fork before it notices TIF_NOTIFY_RESUME and
the new child gets the bogus ->replacement_session_keyring copied by
dup_task_struct(). This is obviously wrong and, if nothing else, this
leads to put_cred(already_freed_cred).change copy_creds() to clear this member. If copy_process() fails
before this point the wrong ->replacement_session_keyring doesn't
matter, exit_creds() won't be called.Cc:

This patch allows caching of the rindex glock. We were previously
setting the GL_NOCACHE bit when the glock was released. That forced
the rindex inode to be invalidated, which caused us to re-read
rindex at the next access. However, it caused the glock to be
unnecessarily bounced around the cluster. This patch allows
the glock to remain cached, but it still causes the rindex to be
re-read once it has been written to by gfs2_grow.Ben and I have tested single-node gfs2_grow cases and I've tested
clustered gfs2_grow cases on my four-node cluster.Signed-off-by: Bob Peterson

Commit f02e8a6596b7 ("module: Sort exported symbols") sorts symbols
placing each of them in its own elf section. This sorting and merging
into the canonical sections are done by the linker.Unfortunately modpost to generate Module.symvers file parses vmlinux.o
(which is not linked yet) and all modules object files (which aren't
linked yet). These aren't sanitized by the linker yet. That breaks
modpost that can't detect license properly for modules.This patch makes modpost aware of the new exported symbols structure.
[ This above is a slightly corrected version of the explanation of the
problem, copied from commit 62a2635610db ("modpost: Fix modpost's
license checking V3"). That commit fixed the problem for module
object files, but not for vmlinux.o. This patch fixes modpost for
vmlinux.o. ]Signed-off-by: Frank Rowand

The task handoff notifier leaks task_struct since it never gets freed
after the callback returns NOTIFY_OK, which means it is responsible for
doing so.It turns out the lowmemorykiller actually doesn't need this notifier at
all. It's used to prevent unnecessary killing by waiting for a thread
to exit as a result of lowmem_shrink(), however, it's possible to do
this in the same way the kernel oom killer works by setting TIF_MEMDIE
and avoid killing if we're still waiting for it to exit.The kernel oom killer will already automatically set TIF_MEMDIE for
threads that are attempting to allocate memory that have a fatal signal.
The thread selected by lowmem_shrink() will have such a signal after the
lowmemorykiller sends it a SIGKILL, so this won't result in an
unnecessary use of memory reserves for the thread to exit.This has the added benefit that we don't have to rely on
CONFIG_PROFILING to prevent needlessly killing tasks.Reported-by: Werner Landgraf

The driver frees the clock samples buffer before stopping the video
buffers queue. If a DQBUF call arrives in-between,
uvc_video_clock_update() will be called with a NULL clock samples
buffer, leading to a crash. This occurs very frequently when using the
webcam with the flash browser plugin.Move clock initialization/cleanup to uvc_video_enable() in order to free
the clock samples buffer after the queue is stopped. Make sure the clock
is reset at resume time to avoid miscalculating timestamps.Signed-off-by: Laurent Pinchart

The commit e399ce77e6e has broken the DVB ABI for xine:
The problem is that xine is expecting every event after a successful
FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless
of whether the tuning process has LOCKed yet. What used to happen is
that the events inherited the initial tuning parameters from the
FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now
not initialised until the status contains the FE_HAS_LOCK bit.You might argue that this behaviour is intentional, except that if an
application other than xine uses the DVB adapter and manages to set the
parameters_out.frequency field to something other than zero, then xine
no longer has any problems until either the adapter is replugged or the
kernel modules reloaded. This can only mean that the
fepriv->parameters_out struct still contains the (stale) tuning
information from the previous application.Signed-off-by: Chris Rankin

Quanta TW3 ODM design, which is also used for the Gigabyte W551 laptop
