Hans Verkuil 10f8dfdcb8 [media] DocBook media typo
V4L2_CID_BASE_LASTP1 should be V4L2_CID_LASTP1. This has probably been wrong
since the earliest days of this documentation until I did a copy-and-paste
and found out that V4L2_CID_BASE_LASTP1 doesn't actually exist :-)

Hans Verkuil 5cbf17f505 [media] DocBook media: fix incorrect note about packed RGB and colorspace
The fact that the pixelformat is using a packed RGB format has nothing
to do with the colorspace that is being used. Those are very different
things. The colorspace decides what color a triplet of RGB numbers
actually map to. E.g. a red color with values (255, 0, 0) is a different
type of red depending on the colorspace. If the original pixelformat was
e.g. YUV in colorspace REC709, then after the conversion to RGB the
colorspace is still REC709. Unless the hardware actually converted the
colorspace as well from REC709 to sRGB, but that rarely if ever happens.

Remove this incorrect comment.

Laurent Pinchart d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

process events on almost all x86 machines, i386 and x86-64). Since this
"document is designed to provide a list of the minimum levels of
software necessary to run the 3.0 kernels" let's just describe that

E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC
                             (aclk333) gets modified to oscclk
                            = 0x1, no change in clocks.
The recommended value of SYSCLK_SYS_PWR_REG before power gating any
domain is 0x0. So we must also restore the clocks while powering on
a domain everytime.

This patch adds the framework for getting the required mux and parent
clocks through a power domain device node. With this patch, while
powering off a domain, parent is set to oscclk and while powering back
on, its re-set to the correct parent which is as per the recommended
pd on/off sequence.

Chen Yucong b27ebf7791 mm:vmscan: update the trace-vmscan-postprocess.pl for event vmscan/mm_vmscan_lru_isolate
When using trace-vmscan-postprocess.pl for checking the file/anon rate
of scanning, we can find that it can not be performed.  At the same
time, the following message will be reported:

  WARNING: Format not as expected for event vmscan/mm_vmscan_lru_isolate
  'file' != 'contig_taken' Fewer fields than expected in format at
  ./trace-vmscan-postprocess.pl line 171, <FORMAT> line 76.

In trace-vmscan-postprocess.pl, (contig_taken, contig_dirty, and
contig_failed) are be associated respectively to (nr_lumpy_taken,
nr_lumpy_dirty, and nr_lumpy_failed) for lumpy reclaim.  Via commit
c53919adc0 ("mm: vmscan: remove lumpy reclaim"), lumpy reclaim had
already been removed by Mel, but the update for
trace-vmscan-postprocess.pl was missed.

 "Another round of ARM fixes.  The largest change here is the L2 changes
  to work around problems for the Armada 37x/380 devices, where most of
  the size comes down to comments rather than code.

  The other significant fix here is for the ptrace code, to ensure that
  rewritten syscalls work as intended.  This was pointed out by Kees
  Cook, but Will Deacon reworked the patch to be more elegant.

  The remainder are fairly trivial changes"

Thomas Petazzoni 98ea2dba65 ARM: 8076/1: mm: add support for HW coherent systems in PL310 cache
When a PL310 cache is used on a system that provides hardware
coherency, the outer cache sync operation is useless, and can be
skipped. Moreover, on some systems, it is harmful as it causes
deadlocks between the Marvell coherency mechanism, the Marvell PCIe
controller and the Cortex-A9.

To avoid this, this commit introduces a new Device Tree property
'arm,io-coherent' for the L2 cache controller node, valid only for the
PL310 cache. It identifies the usage of the PL310 cache in an I/O
coherent configuration. Internally, it makes the driver disable the
outer cache sync operation.

Note that technically speaking, a fully coherent system wouldn't
require any of the other .outer_cache operations. However, in
practice, when booting secondary CPUs, these are not yet coherent, and
therefore a set of cache maintenance operations are necessary at this
point. This explains why we keep the other .outer_cache operations and
only ->sync is disabled.

While in theory any write to a PL310 register could cause the
deadlock, in practice, disabling ->sync is sufficient to workaround
the deadlock, since the other cache maintenance operations are only
used in very specific situations.

Contrary to previous versions of this patch, this new version does not
simply NULL-ify the ->sync member, because the l2c_init_data
structures are now 'const' and therefore cannot be modified, which is
a good thing. Therefore, this patch introduces a separate
l2c_init_data instance, called of_l2c310_coherent_data.
