Merge branch 'linus' into x86/spinlocks
Done to prevent this failure of an Octopus merge:
Added arch/arm/include/asm/byteorder.h in both, but differently.
ERROR: Merge conflict in arch/arm/include/asm/byteorder.h
Auto-merging include/asm-x86/spinlock.h
ERROR: Merge conflict in include/asm-x86/spinlock.h
fatal: merge program failed
