  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.
