Subject: [RFC][PATCH 0/2] convert s390 to generic mmu_gather

Hi Peter,

as an add-on for the TLB flushing changes two patches to make
s390 use the generic mmu_gather code as well. I let it run for
a few hours with several TLB stress tests, no fallout so far.
It certainly can use more testing but it looks ok to me.

  asm-generic/tlb: introduce HAVE_MMU_GATHER_NO_GATHER
  s390/tlb: convert to generic mmu_gather
