2c0c9da02a Btrfs: fix "mutually exclusive op is running" error code
The error code that is returned in response to starting a mutually
exclusive operation when there is one already running got silently
changed from EINVAL to EINPROGRESS by 5ac00add.  Returning EINPROGRESS
to, say, add_dev, when rm_dev is running is misleading.  Furthermore,
the operation itself may want to use EINPROGRESS for other purposes.

ed0fb78fb6 Btrfs: bring back balance pause/resume logic
Balance pause/resume logic got broken by 5ac00add (went in into 3.8-rc1
as part of dev-replace merge).  Offending commit took a stab at making
mutually exclusive volume operations (add_dev, rm_dev, resize, balance,
replace_dev) not block behind volume_mutex if another such operation is
in progress and instead return an error right away.  Balancing front-end
relied on the blocking behaviour, so the fix is ugly, but short of a
complete rework, it's the best we can do.

15653371c6 ARM: DMA: Fix struct page iterator in dma_cache_maint() to work with sparsemem
Subhash Jadavani reported this partial backtrace:
  Now consider this call stack from MMC block driver (this is on the ARMv7
  based board):

  [<c001b50c>] (v7_dma_inv_range+0x30/0x48) from [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c)
  [<c0017b8c>] (dma_cache_maint_page+0x1c4/0x24c) from [<c0017c28>] (___dma_page_cpu_to_dev+0x14/0x1c)
  [<c0017c28>] (___dma_page_cpu_to_dev+0x14/0x1c) from [<c0017ff8>] (dma_map_sg+0x3c/0x114)

This is caused by incrementing the struct page pointer, and running off
the end of the sparsemem page array.  Fix this by incrementing by pfn
instead, and convert the pfn to a struct page.

2521686539 ACPI, APEI: Fixup incorrect 64-bit access width firmware bug
The bit width check was introduced by 15afae60 (ACPI, APEI: Fix
incorrect APEI register bit width check and usage), and a fixup
for incorrect 32-bit width memory address was given by f712c71
(ACPI, APEI: Fixup common access width firmware bug). Now there
is a similar symptom:

[Firmware Bug]: APEI: Invalid bit width + offset in GAR [0x12345000/64/0/3/0]

Another bogus BIOS reports an incorrect 64-bit width in trigger table.
Thus, apply to a similar workaround for 64-bit width memory address.

bdcc612752 ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls
During the migration to the common clock framework, calls to the
functions omap2xxx_clkt_vps_late_init() were not preserved for
OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and
"curr_prcm_set" to be uninitialised on boot. On reboot, this causes the
following error message to be displayed because the appropriate MPU
clock frequency (derived from sys_ck_rate) cannot be found.

"Could not set MPU rate to 4294MHz"

Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the
OMAP2420 and OMAP2430 clock initialisation code.

2a8d53916b ALSA: hda - Fix the wrong adc_idx for capture source
The patch "ALSA: hda - fix wrong adc_idx in generic parser" fixed the
adc_idx for the capture volume and capture switch controls.  But also
modified the adc_idx retrieval for the capture source controls
wrongly.  As multiple capture source controls are created in a single
shot with counts > 1, the id.index doesn't contain the real value.
The real index has to be taken via snd_ctl_get_ioffidx() as in the
original code.

This patch reverts the fixes partially to recover from the
regression.

a90229e051 ALSA: hda - Consolidate cap_sync_hook and capture_switch_hook
Two hooks in hda_gen_spec, cap_sync_hook and capture_switch_hook, play
very similar roles.  The only differences are that the former is
called more often (e.g. at init or switching capsrc) while the latter
can take an on/off argument.

As a more generic implementation, consolidate these two hooks, and
pass snd_ctl_elem_value pointer as the second argument.  If the
secondary argument is non-NULL, it can take the on/off value, so the
caller handles it like the former capture_switch_hook.  If it's NULL,
it's called in the init or capsrc switch case.

powernow-k8 couldn't handoff properly to acpi-cpufreq leading to
running without P-state support (i.e., cores are constantly in P0).

To alleaviate that, we need to make powernow-k8 depend on acpi-cpufreq
so that acpi-cpufreq is always present.

b88a634a90 ACPI / cpuidle: Fix NULL pointer issues when cpuidle is disabled
If cpuidle is disabled, that means that:

	per_cpu(acpi_cpuidle_device, pr->id)

is set to NULL as the acpi_processor_power_init ends up failing at

	 retval = cpuidle_register_driver(&acpi_idle_driver)

(in acpi_processor_power_init) and never sets the per_cpu idle
device.  So when acpi_processor_hotplug on CPU online notification
tries to reference said device it crashes:

The 'intel_idle_probe' probes the CPU and sets the CPU notifier.

in cpuidle_register_driver), we stop loading, but we neglect
to unregister the CPU notifier.  This means that during CPU

091a62c9b3 usb: musb: cppi_dma: drop '__init' annotation
This patch fixes the following:

WARNING: vmlinux.o(.text+0x1e709c): Section mismatch in reference from the funct
ion dma_controller_create() to the function .init.text:cppi_controller_start()
The function dma_controller_create() references
the function __init cppi_controller_start().
This is often because dma_controller_create lacks a __init
annotation or the annotation of cppi_controller_start is wrong.

This warning is there due to the deficiency in the commit 07a67bbb (usb: musb:
Make dma_controller_create __devinit).

Since the start() method is only called from musb_init_controller() which is
not annotated, drop '__init' annotation from cppi_controller_start() and also
cppi_pool_init() since it gets called from that function, to avoid another
section mismatch warning...

In the current generic parser code, we look for the (mic) boost
controls only on input pins.  But many codecs assign the boost volume
to a widget connected to each input pin instead of the input amp of

In this patch, the parser tries to look through more widgets connected
to the pin and find a boost amp.

Since the imux table entries can be a subset of autocfg.input table,
the indices of these aren't always same.  For passing the proper index
value of autocfg.input at creating input ctl labels (via
snd_hda_autocfg_input_label()), keep the corresponding autocfg.input
idx value in the index field of each imux item, which isn't used in
the generic driver.

Also, this makes easier to check the invalid imux pin for stereo mix.
