Merge branch 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux into v4l_for_linus

2015-04-21T12:44:55+00:00

* 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux: (9717 commits)
  media-bus: Fixup RGB444_1X12, RGB565_1X16, and YUV8_1X24 media bus format
  hexdump: avoid warning in test function
  fs: take i_mutex during prepare_binprm for set[ug]id executables
  smp: Fix error case handling in smp_call_function_*()
  iommu-common: Fix PARISC compile-time warnings
  sparc: Make LDC use common iommu poll management functions
  sparc: Make sparc64 use scalable lib/iommu-common.c functions
  Break up monolithic iommu table/lock into finer graularity pools and lock
  sparc: Revert generic IOMMU allocator.
  tools/power turbostat: correct dumped pkg-cstate-limit value
  tools/power turbostat: calculate TSC frequency from CPUID(0x15) on SKL
  tools/power turbostat: correct DRAM RAPL units on recent Xeon processors
  tools/power turbostat: Initial Skylake support
  tools/power turbostat: Use $(CURDIR) instead of $(PWD) and add support for O= option in Makefile
  tools/power turbostat: modprobe msr, if needed
  tools/power turbostat: dump MSR_TURBO_RATIO_LIMIT2
  tools/power turbostat: use new MSR_TURBO_RATIO_LIMIT names
  Bluetooth: hidp: Fix regression with older userspace and flags validation
  config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected
  perf/x86/intel/pt: Fix and clean up error handling in pt_event_add()
  ...

That solves several merge conflicts:
	Documentation/DocBook/media/v4l/subdev-formats.xml
	Documentation/devicetree/bindings/vendor-prefixes.txt
	drivers/staging/media/mn88473/mn88473.c
	include/linux/kconfig.h
	include/uapi/linux/media-bus-format.h

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.

Merge Linus master into drm-next

2015-04-20T03:05:20+00:00

The merge is clean, but the arm build fails afterwards,
due to API changes in the regulator tree.

I've included the patch into the merge to fix the build.

media-bus: Fixup RGB444_1X12, RGB565_1X16, and YUV8_1X24 media bus format

2015-04-20T01:23:56+00:00

Change the constant values for RGB444_1X12, RGB565_1X16, and YUV8_1X24 media
bus formats in anticipation of a merge conflict with the media tree, where
the old values are already taken by RBG888_1X24, RGB888_1X32_PADHI, and
VUY8_1X24, respectively.

[media] v4l2_plane_pix_format: use u32 bytesperline instead of u16

2015-04-03T02:54:47+00:00

While running v4l2-compliance tests on vivid I suddenly got errors due to
a call to vmalloc_user with size 0 from vb2.

Digging deeper into the cause I discovered that this was due to the fact that
struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32.

The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32
bit pixelformat.

So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And
bytesperline * height is suddenly 0 as well. While the vivid driver may be
a virtual driver, it is to be expected that this limit will be hit for real
hardware as well in the near future: 8k deep-color video will already reach
it.

The solution is to change the type to __u32. The only drivers besides vivid
that use the multiplanar API are little-endian ARM and SH platforms (exynos,
ti-vpe, vsp1), so this is safe.
