Subject: [PATCH 0/4] Drivers: hv: balloon: fix WS2012 memory hotplug issues and do some cleanup

Crashes with Hyper-V balloon driver are reported with WS2012 (non-R2),
hosts I was able to identify two issues which I fix with first two patches
of this series. Patches 3 removes ol_waitevent which is not needed since
we have in-kernel memory onlining, patch 4 gets rid of ha_region_mutex
by doing the locking fine-grained with a spinlock.

Vitaly Kuznetsov (4):
  Drivers: hv: balloon: keep track of where ha_region starts
  Drivers: hv: balloon: account for gaps in hot add regions
  Drivers: hv: balloon: get rid on ol_waitevent
  Drivers: hv: balloon: replace ha_region_mutex with spinlock
