Linus Torvalds 1609d7604b 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.
