Pull mailbox framework from Jassi Brar:
"A framework for Mailbox controllers and clients have been cooking for
more than a year now.
Everybody in the CC list had been copied on patchset revisions and
most of them have made sounds of approval, though just one concrete
Reviewed-by. The patchset has also been in linux-next for a couple of
weeks now and no conflict has been reported. The framework has the
backing of at least 5 platforms, though I can't say if/when they
upstream their drivers (some businesses have 'changed')"
(Further acked-by by Arnd Bergmann and Suman Anna in the pull request
thread)

As PCM core handles the multiple linked streams in parallel, lockdep
gets confused (partly because of weak annotations) and spews the
false-positive warnings. This hasn't been a problem for long time but
the latest PCM lock path update seems to have woken up a sleeping
dog.
Here is an attempt to paper over this issue: pass the lock subclass
just calculated from the depth in snd_pcm_action_group(). Also, a
(possibly) wrong lock subclass set in snd_pcm_action_lock_mutex() is
dropped, too.

The picvue_proc.c file creates the /proc interface for the PICVUE LCD
display driver. As a result of which, it needs to depend on the PROC_FS

CONFIG_PROC_FS is not enabled.

Pull more powerpc updates from Michael Ellerman:
"Here's some more updates for powerpc for 3.18.

Probably the most interesting fix is the sys_call_table one, which

Commit 08a07904e1828 ("MIPS: math-emu: Remove most ifdefery") removed
the #ifdef ISA conditions and switched to runtime detection. However,
according to the instruction set manual, the cop1x_op instructions are
available in >=MIPS32r2 as well. This fixes a problem on MIPS32r2
with the ntpd package which failed to execute with a SIGILL exit code due
to the fact that a madd.d instruction was not being emulated.

regulator is optional, but when not present, a scary message "failed

severity of the message from dev_warn() to dev_dbg() and we reword the
message to not be as scary.

This commit extends the cpufreq_driver structure with an additional
'void *driver_data' field that can be filled by the ->probe() function
of a cpufreq driver to pass additional custom information to the
driver itself.
A new function called cpufreq_get_driver_data() is added to allow a
cpufreq driver to retrieve those driver data, since they are typically
needed from a cpufreq_policy->init() callback, which does not have
access to the cpufreq_driver structure. This function call is similar
to the existing cpufreq_get_current_driver() function call.

This change adds a new flag, ACPI_EVENT_FLAGS_HAS_HANDLER to the
