Merge tag 'for-linus' of git://git./virt/kvm/kvm

Pull kvm fixes from Paolo Bonzini:
 "The main change here is a revert of reverts. We recently simplified
  some code that was thought unnecessary; however, since then KVM has
  grown quite a few cond_resched()s and for that reason the simplified
  code is prone to livelocks---one CPUs tries to empty a list of guest
  page tables while the others keep adding to them. This adds back the
  generation-based zapping of guest page tables, which was not
  unnecessary after all.

  On top of this, there is a fix for a kernel memory leak and a couple
  of s390 fixlets as well"
