[media] mt9p031: Fix BLC configuration restore when disabling test pattern
Auto BLC and BLC digital offset are disabled when enabling the test
pattern and must be restored when disabling it. The driver does so by
calling the set control handler on the auto BLC and BLC offset controls,
but this programs the hardware with the new value of those controls, not
the current value. Fix this by writing to the registers directly.

[media] v4l: ti-vpe: Fix some params in VPE data descriptors
Some parameters of the VPE descriptors were understood incorrectly. They are now
fixed. The fixes are explained as follows:
- When adding an inbound data descriptor to the VPDMA descriptor list, we intend
to use c_rect as the cropped region fetched by VPDMA. Therefore, c_rect->width
shouldn't be used to calculate the line stride, the original image width
should be used for that. We add a 'width' argument which gives the buffer
width in memory.
- frame_width and frame_height describe the complete width and height of the
client to which the channel is connected. If there are multiple channels
fetching data and providing to the same client, the above 2 arguments should
be the width and height of the region covered by all the channels. In the case
where there is only one channel providing pixel data to the client
(like in VPE), frame_width and frame_height should be the cropped width and
cropped height respectively. The calculation of these params is done in the
vpe driver now.
- start_h and start_v is also used in the case of multiple channels to describe
where each channel should start filling pixel data. We don't use this in VPE,
and pass 0s to the vpdma_add_in_dtd() helper.
- Some minor changes are made to the vpdma_add_out_dtd() helper. The c_rect
param is used for specifying the 'composition' target, and 'width' is added
to calculate the line stride.

[media] v4l: ti-vpe: register video device only when firmware is loaded
vpe fops(vpe_open in particular) should be called only when VPDMA firmware
is loaded. File operations on the video device are possible the moment it is
registered.
Currently, we register the video device for VPE at driver probe, after calling
a vpdma helper to initialize VPDMA and load firmware. This function is
non-blocking(it calls request_firmware_nowait()), and doesn't ensure that the
firmware is actually loaded when it returns.
We remove the device registration from vpe probe, and move it to a callback
provided by the vpe driver to the vpdma library, through vpdma_create().
The ready field in vpdma_data is no longer needed since we always have firmware
loaded before the device is registered.
A minor problem with this approach is that if the video_register_device
fails(which doesn't really happen), the vpe platform device would be registered.
however, there won't be any v4l2 device corresponding to it.

One of this pointer is used by follow_pte() called by follow_pfn()

"Still fixing regressions (partly by reverting commits that broke
things for people), fixing other stable-candidate bugs and adding some
blacklist entries for ACPI video and _OSI.
Two ACPICA regression fixes (one recent and one for a 3.14 commit), a
fix for an ACPI-related regression in TPM (introduced in 3.14), a
revert of the ACPI AC driver conversion in 3.13 that went wrong for an
unknown reason, two reverts of commits that attempted to remove an old
user space interface in /proc and broke some utilities, in 3.13 too, a
fix for a CPU hotplug bug in the ACPI processor driver (stable
material), two (stable candidate) fixes for intel_pstate and a few new
blacklist entries, mostly for systems that shipped with Windows 8.
Specifics:
- ACPICA fix for a stale pointer access introduced by a recent commit
in the XSDT validation code from Lv Zheng.
- ACPICA fix for the default value of the command line switch to
favor 32-bit FADT addresses (in case there's a conflict between a
64-bit and a 32-bit address). The previous default was that the
32-bit version would take precedence and we tried to change it to
the other way around and it didn't work. From Lv Zheng.
- A TPM commit related to ACPI _DSM in 3.14 caused the driver to
refuse to load if a specific _DSM was missing and that broke resume
from system suspend on Chromebooks that require the TPM hardware to
be restored to a working state during resume by the OS. Restore
the old behavior to load the driver if the _DSM in question is not
present, but prevent it from using the feature the _DSM is for.
- ACPI AC driver conversion in 3.13 broke thermal management on at
least one machine and has to be reverted. From Guenter Roeck.
- Two reverts of 3.13 commits that attempted to remove the old ACPI
battery interface in /proc, but turned out to break some utilities
still using that interface. From Lan Tianyu.
- ACPI processor driver fix to prevent acpi_processor_add() from
modifying the CPU device's .offline field which leads to breakage
if the initial online of the CPU fails. From Igor Mammedov.
- Two intel_pstate fixes, one to take a BayTrail documentation update
into account and one to avoid forcing the maximum P-state on init
which causes CPU PM trouble on systems with P-states coordination
when one of the CPU cores is initialized after an offline/online
cycle triggered by user space. Both stable candidates, from Dirk
Brandewie.
- Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
from Aaron Lu.

Win8 that need to use native backlight so that it can be controlled

Btrfs: send, fix incorrect ref access when using extrefs
When running send, if an inode only has extended reference items
associated to it and no regular references, send.c:get_first_ref()
was incorrectly assuming the reference it found was of type
BTRFS_INODE_REF_KEY due to use of the wrong key variable.
This caused weird behaviour when using the found item has a regular
reference, such as weird path string, and occasionally (when lucky)
a crash:

Btrfs: fix EIO on reading file after ioctl clone works on it
For inline data extent, we need to make its length aligned, otherwise,
we can get a phantom extent map which confuses readpages() to return -EIO.
This can be detected by xfstests/btrfs/035.

scripts/checksyscalls.sh: Make renameat optional
The new renameat2 syscall provides all the functionality of renameat
with an additional flags argument, so make renameat optional so that
future architectures can omit it without getting a warning.
This patch doesn't affect existing architectures.
