    Linus Torvalds authored
    Pull unified TLB flushing from Ingo Molnar:
     "This contains the generic mmu_gather feature from Peter Zijlstra,
      which is an all-arch unification of TLB flushing APIs, via the
      following (broad) steps:
    
       - enhance the <asm-generic/tlb.h> APIs to cover more arch details
    
       - convert most TLB flushing arch implementations to the generic
         <asm-generic/tlb.h> APIs.
    
       - remove leftovers of per arch implementations
    
      After this series every single architecture makes use of the unified
      TLB flushing APIs"
