ed2617585f fs/compat_ioctl.c: fix build error when !BLOCK
No driver uses SG_SET_TRANSFORM any more in Linux, since the ide-scsi
driver was removed in 2.6.29. The compat-ioctl cleanup series moved
the handling for this around, which broke building without CONFIG_BLOCK.

Just remove the code handling it for compat mode.

385e3ed4f0 alloc_file(): simplify handling of mnt_clone_write() errors
When alloc_file() and init_file() were combined, the error handling of
mnt_clone_write() was taken into alloc_file() in a somewhat obfuscated
way.  Since we don't use the error code for anything except warning,
we might as well warn directly without an extra variable.

3321c2bcea ARM: 5849/1: ARMv7: fix Oprofile events count
On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs
and so to decrease the risk of errata #628216 from appearing.
The effect of setting the PMNC_D bit is that the CCNT counter
is divided by 64, making the program counter events count
inaccurate.
The new OMAP3 r4 cores should have that errata fixed.

The PMNC_D bit should not be set, this patch fixes it.

b6aa179334 ASoC: sh: FSI:: don't check platform_get_irq's return value against zero
platform_get_irq returns -ENXIO on failure, so !irq was probably
always true.  Better use (int)irq <= 0.  Note that a return value of
zero is still handled as error even though this could mean irq0.

This is a followup to 305b3228f9 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

43bab25ced ACPI: processor: change acpi_processor_set_pdc() interface
When calling _PDC, we really only need the handle to the processor
to call the method; we don't look at any other parts of the
struct acpi_processor * given to us.

In the early path, when we walk the namespace, we are given the
handle directly, so just pass it through to acpi_processor_set_pdc()
without stuffing it into a wasteful struct acpi_processor allocated
on the stack each time

This saves 2834 bytes of stack.

Update the interface accordingly.

6c5807d7bc ACPI: processor: finish unifying arch_acpi_processor_init_pdc()
The only thing arch-specific about calling _PDC is what bits get
set in the input obj_list buffer.

There's no need for several levels of indirection to twiddle those
bits. Additionally, since we're just messing around with a buffer,
we can simplify the interface; no need to pass around the entire
struct acpi_processor * just to get at the buffer.

78f1699659 ACPI: processor: call _PDC early
We discovered that at least one machine (HP Envy), methods in the DSDT
attempt to call external methods defined in a dynamically loaded SSDT.

Unfortunately, the DSDT methods we are trying to call are part of the
EC initialization, which happens very early, and the the dynamic SSDT
is only loaded when a processor _PDC method runs much later.

This results in namespace lookup errors for the (as of yet) undefined
methods.

Since Windows doesn't have any issues with this machine, we take it
as a hint that they must be evaluating _PDC much earlier than we are.

Thus, the proper thing for Linux to do should be to match the Windows
implementation more closely.

Provide a mechanism to call _PDC before we enable the EC. Doing so loads
the dynamic tables, and allows the EC to be enabled correctly.

The ACPI processor driver will still evaluate _PDC in its .add() method
to cover the hotplug case.

                        }
                    }
LBTN is used to store the index of the brightness level in the _BCL.
GCBL is a method that convert the percentage value to the index value.
If _OSI(Windows 2009) is not disabled, LBTN is stored a percentage
value which is surely beyond the end of _BCL package.

ad8decb7f5 ALSA: jazz16: Add support for Media Vision Jazz16 chipset
This is one of Sound Blaster Pro compatible chipsets which is supported
by Linux OSS driver and was missing native supoort for ALSA.

The Jazz16 audio codec is Crystal CS4216 which is capable
of playback and recording up to 48 kHz stereo.

db8cf334f6 ALSA: sbawe: fix memory detection
Memory amount is increased before a successful write-read
sequence is done. Thus, 512 kB of onboard memory is detected
on memoryless cards like SB32.

Move the increasing of memory counter after successful read
is done.

40962d7c74 ALSA: fix incorrect rounding direction in snd_interval_ratnum()
The direction of rounding is incorrect in the snd_interval_ratnum()
It was detected with following parameters (sb8 driver playing
8kHz stereo file):
 - num is always 1000000
 - requested frequency rate is from 7999 to 7999 (single frequency)

The first loop calculates div_down(num, freq->min) which is 125.
Thus, a frequency range's minimum value is 1000000 / 125 = 8000 Hz.
The second loop calculates div_up(num, freq->max) which is 126
The frequency range's maximum value is 1000000 / 126 = 7936 Hz.
The range maximum is lower than the range minimum so the function
fails due to empty result range.

f5de24b06a ALSA: HDA: add powersaving hook for Realtek
The current Realtek code makes no specific provision for turning stuff
off. The codec chip is placed into low-power mode generically, but this
doesn't turn off any external hardware connected to it, in particular
external amplifiers.

This patch creates a hook function that is called by the codec
suspend/resume functions. It ought to disable any external hardware in a
device-specific way. I've implemented a generic ALC889 function that
sets the EAPD pin properly, and used it for the Acer Aspire 8930G which
can benefit from this feature.

On my laptop, this results in ~0.5W extra savings.

556eea9a92 ALSA: HDA: remove useless mixers on Aspire 8930G
This patch removes some extra mixers that do nothing on the Acer Aspire
8930G.

The CD mixer is useless because the SATA DVD/Blu-Ray drive has no analog
audio output, and the Side mixer is useless because we max out at 6ch
anyway.

0f86a228f4 ALSA: HDA: simplify Aspire 8930G verb array
This patch just simplifies the 8930G verb array a bit. Just use the
common ALC889 EAPD verb array to make things more consistent. The file
is already huge enough already.
