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.
