# Merge: 1f9c632cde0c a9c20bb0206a
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     
#     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"
