Make s5p_jpeg_parse_hdr function capable of parsing
"YCbCr subsampling" field of a jpeg file header. Store the
parsed value in the context.
The information about source JPEG subsampling is required to
make validation of destination format possible, which must be
conducted for exynos4x12 device as the decoding process will
not succeed if the destination format is set to YUV with
subsampling lower than the one of the source JPEG image.
With this knowledge the driver can adjust the destination format
appropriately.

Replace calls to sec_reg* helpers with direct usage of regmap API. The
sec_reg* helpers are error-prone as they mix u8 with unsigned int and
order of some of parameters (val and mask in sec_reg_update()).
Also the helpers do not give any way of useful abstraction as they just
call corresponding regmap function.
This patch replaces:
- sec_reg_read() with regmap_read(),
- sec_reg_write() with regmap_write(),
- sec_reg_update() with regmap_update_bits().

Pull perf/core improvements and refactorings from Arnaldo Carvalho de Melo:
New features:
. In perf timechart:
- Add backtrace support to CPU info
. Print pid along the name
. Add support for CPU topology
. Add new option --highlight'ing threads, be it by name or,
if a numeric value is provided, that run more than given duration.
From Stanislav Fomichev.
Refactorings:
. Rename some struct DSO binary_type related members and methods,
to clarify its purpose and need for differentiation from symtab_type,
i.e. one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from.
. Convert to new topic libraries, starting with an API one (sysfs, debugfs,
etc), renaming liblk in the process, from Borislav Petkov.
. Get rid of some more panic() like error handling in libtraceevent,
from Namhyung Kim.

But only when we indeed set up a gtt mapping. We need this since the
vma also holds a pages_pin_count, on top of the unconditional

This should avoid a pages_pin_count underrun when cleaning up
framebuffers objects taken over from the BIOS.

Commit caaa4c804f ("KVM: PPC: Book3S HV: Fix physical address
calculations") unfortunately resulted in some low-order address bits
getting dropped in the case where the guest is creating a 4k HPTE
and the host page size is 64k. By getting the low-order bits from
hva rather than gpa we miss out on bits 12 - 15 in this case, since
hva is at page granularity. This puts the missing bits back in.

when a userspace applications calls the VIDIOC_STREAMON ioctl. The
V4L2 core calls the soc_camera_streamon function, which is responsible
for starting the video stream. It does so by first starting the atmel-isi
host by a call to the vb2_streamon function, and then starting the sensor
by a call to the video.s_stream sensor subdev operation.
That means we wait for a SOF in start_streaming() before call sensor's
s_stream(). It is possible no VSYNC interrupt arrive as the sensor
hasn't been started yet.
To avoid such case, this patch remove the code to wait for the VSYNC
interrupt. And such code is not necessary.
