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
