6fa6183aef Clean up related changes for v3.10 merge window.
Mostly clock and PM related with removal of now unused
 DMA channel definitions. The clock change to use SoC
 specific lists will make it a little bit easier to
 add support for new SoCs variants without having to patch
 all over the place.

fd1c078614 ARM: OMAP4: Fix the init code to have OMAP4460 errata available in DT build

bases to be available for the bug work around. In current code, dt
case these bases are not initialized leading to failure of the
errata work-around.

Fix it by extracting the bases from dt blob and populating them.

Hence the l4_wakeup static dependency with MPU can  can be removed

power savings perspective, it isn't an ideal workaround.

On OMAP platform, FIQ is reserved for secure environment only. If at all
the FIQ needs to be disabled, it involves going through security

On GP devices too, the fiq is disabled for non-secure software.

Commit 1d9d8639c0 ("perf,x86: fix kernel crash with PEBS/BTS after
suspend/resume") fixed a crash when doing PEBS performance profiling
after resuming, but in using init_debug_store_on_cpu() to restore the
DS_AREA mtrr it also resulted in a new WARN_ON() triggering.

init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU
cross-calls to do the MSR update.  Which is not really valid at the
early resume stage, and the warning is quite reasonable.  Now, it all
happens to _work_, for the simple reason that smp_call_function_single()
ends up just doing the call directly on the CPU when the CPU number
matches, but we really should just do the wrmsr() directly instead.

This duplicates the wrmsr() logic, but hopefully we can just remove the
wrmsr_on_cpu() version eventually.

3e762c86b3 arm: mach-orion5x: use mv_mbus_dram_info() in PCI code
The PCI code was directly accessing the orion_mbus_dram_info structure
to get access to a description of the SDRAM chip selects in order to
configure the PCIe -> SDRAM address decoding windows.

However, with the introduction of the mvebu-mbus driver, we are going
to remove this global structure and instead leave only the exported
mv_mbus_dram_info() function to access this description of the SDRAM
chip selects. Therefore, we simply switch to using this API.

efaaa98d30 arm: plat-orion: only build addr-map.c when needed
-flagmail-match: MVEBU
X-flagmail-match: KIRKWOOD
X-flagmail-match: DOVE

For now, addr-map.c is needed by all 5 Marvell EBU
sub-architectures. However, we are going to introduce the orion-mbus
driver, which will replace the address decoding code from
addr-map.c. In order to ease the migration process, we will do that
one sub-architecture at a time, which will require us to remove the
compilation of addr-map.c one sub-architecture at a time.

Therefore, we split the unconditional obj-y inclusion of addr-map.c
into 5 conditionals obj-$(CONFIG_...) lines, one per sub-architecture.

3b2775942d Btrfs: fix warning of free_extent_map
Users report that an extent map's list is still linked when it's actually
going to be freed from cache.

The story is that

a) when we're going to drop an extent map and may split this large one into
smaller ems, and if this large one is flagged as EXTENT_FLAG_LOGGING which means
that it's on the list to be logged, then the smaller ems split from it will also
be flagged as EXTENT_FLAG_LOGGING, and this is _not_ expected.

b) we'll keep ems from unlinking the list and freeing when they are flagged with
EXTENT_FLAG_LOGGING, because the log code holds one reference.

The end result is the warning, but the truth is that we set the flag
EXTENT_FLAG_LOGGING only during fsync.

So clear flag EXTENT_FLAG_LOGGING for extent maps split from a large one.

This patch fixes a kernel crash when using precise sampling (PEBS)
after a suspend/resume. Turns out the CPU notifier code is not invoked
on CPU0 (BP). Therefore, the DS_AREA (used by PEBS) is not restored properly
by the kernel and keeps it power-on/resume value of 0 causing any PEBS
measurement to crash when running on CPU0.

The workaround is to add a hook in the actual resume code to restore
the DS Area MSR value. It is invoked for all CPUS. So for all but CPU0,
the DS_AREA will be restored twice but this is harmless.

6d3073e124 ALSA: hda - Fix missing EAPD/GPIO setup for Cirrus codecs
During the transition to the generic parser, the hook to the codec
specific automute function was forgotten.  This resulted in the silent
output on some MacBooks.

57220bc1f5 sound: sequencer: cap array index in seq_chn_common_event()
"chn" here is a number between 0 and 255, but ->chn_info[] only has
16 elements so there is a potential write beyond the end of the
array.

If the seq_mode isn't SEQ_2 then we let the individual drivers
(either opl3.c or midi_synth.c) handle it.  Those functions all
do a bounds check on "chn" so I haven't changed anything here.
The opl3.c driver has up to 18 channels and not 16.

037154105e mfd: twl4030-madc: Remove __exit_p annotation
4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation
on the twl4030_madc_remove function, but left an __exit_p() present on the
pointer to this function. Using __exit_p was as wrong with the devexit in
place as it is now, but now we get a gcc warning about an unused function.

In order for the twl4030_madc_remove to work correctly in built-in code, we
have to remove the __exit_p.
