Merge branch 'linus' into locking/core, to resolve conflicts

 Conflicts:
	include/linux/mm_types.h
	mm/huge_memory.c

I removed the smp_mb__before_spinlock() like the following commit does:

  8b1b436dd1cc ("mm, locking: Rework {set,clear,mm}_tlb_flush_pending()")

and fixed up the affected commits.
