video: s3c-fb: Add support EXYNOS4 FIMD
This patch adds struct s3c_fb_driverdata s3c_fb_data_exynos4 for EXYNOS4
and adds lcd clock gating support.
FIMD driver needs two clocks for FIMD IP and LCD pixel clock. Previously,
both clocks are provided by using bus clock such as HCLK. However, EXYNOS4
can not select HCLK for LCD pixel clock because the EXYNOS4 FIMD IP does not
have the CLKSEL bit of VIDCON0. So, FIMD driver should provide the lcd clock
using SCLK_FIMD as LCD pixel clock for EXYNOS4.
The driver selects enabling lcd clock according to has_clksel which means
the CLKSEL bit of VIDCON0. If there is has_clksel, the driver will not
enable the lcd clock using SCLK_FIMD because bus clock using HCLK is used
a LCD pixel clock.

udlfb: Add module option to do without shadow framebuffer
By default, udlfb allocates a 2nd buffer to shadow what's across
the bus on the USB device. It can operate without this shadow,
but then it cannot tell which pixels have changed, and must send all.
Saves host memory, but worsens the USB 2.0 bus bottleneck.
This option allows users in very low memory situations (e.g.
bifferboard) to optionally turn off this shadow framebuffer.

ext4: flush any pending end_io requests before DIO reads w/dioread_nolock
There is a race between ext4 buffer write and direct_IO read with
dioread_nolock mount option enabled. The problem is that we clear
PageWriteback flag during end_io time but will do
uninitialized-to-initialized extent conversion later with dioread_nolock.
If an O_direct read request comes in during this period, ext4 will return
zero instead of the recently written data.
This patch checks whether there are any pending uninitialized-to-initialized
extent conversion requests before doing O_direct read to close the race.
Note that this is just a bandaid fix. The fundamental issue is that we
clear PageWriteback flag before we really complete an IO, which is
problem-prone. To fix the fundamental issue, we may need to implement an
extent tree cache that we can use to look up pending to-be-converted extents.

indicated in the MI_FLUSH command. However starting with Ivybridge, the

ALSA: usb-audio - Fix missing mixer dB information
The recent fix for testing dB range at the mixer creation time seems
to cause regressions in some devices. In such devices, reading the dB
info at probing time gives an error, thus both dBmin and dBmax are still
zero, and TLV flag isn't set although the later read of dB info succeeds.
This patch adds a workaround for such a case by assuming that the later
read will succeed. In future, a similar test should be performed in a
case where a wrong dB range is seen even in the later read.

drivers/ata/sata_dwc_460ex.c: add missing kfree
Currently, error handling code in this function calls the function
sata_dwc_port_stop, but this function has essentially no effect if hsdevp
has not been stored in ap, which is the case throughout this function. The
only effect is to print a debugging message including ap->print_id.
The code is rewritten to not call sata_dwc_port_stop, but instead to jump
to a local label that prints the original error message and the print_id
information. In the case where hsdevp has been already allocated (but not
yet stored in ap), this value is freed as well.

Btrfs: set i_size properly when fallocating and we already
xfstests exposed a problem with preallocate when it fallocates a range that
already has an extent. We don't set the new i_size properly because we see that
we already have an extent. This isn't right and we should update i_size if the
space already exists. With this patch we now pass xfstests 075. Thanks,

btrfs: btrfs_permission's RO check shouldn't apply to device nodes
This patch tightens the read-only access checks in btrfs_permission to
match the constraints in inode_permission. Currently, even though the
device node itself will be unmodified, read-write access to device nodes
is denied to when the device node resides on a read-only subvolume or a
is a file that has been marked read-only by the btrfs conversion utility.
With this patch applied, the check only affects regular files,
directories, and symlinks. It also restructures the code a bit so that
we don't duplicate the MAY_WRITE check for both tests.

ALSA: hda - Add "PCM" volume to vmaster slave list
The new parser may use "PCM" volume, but it was missing the vmaster
slave list, thus "Master" volume didn't control it.

perf tools: Add group event scheduling option to perf record/stat
Group event scheduling command line option is missing in perf
record/stat.
Add it to perf record/stat, which is same as in perf top.
