Merge tag 'kvm-s390-master-5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into kvm-master (2019-09-14 09:25:30 +0200)
----------------------------------------------------------------
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.
