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

* '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.
