Subject: [PATCH v4 0/2] vhost: support more than 64 memory regions

changes since v3:
  * rebased on top of vhost-next branch
changes since v2:
  * drop cache patches for now as suggested
  * add max_mem_regions module parameter instead of unconditionally
    increasing limit
  * drop bsearch patch since it's already queued

References to previous versions:
v2: https://lkml.org/lkml/2015/6/17/276
v1: http://www.spinics.net/lists/kvm/msg117654.html

Series allows to tweak vhost's memory regions count limit.

It fixes VM crashing on memory hotplug due to vhost refusing
accepting more than 64 memory regions with max_mem_regions
set to more than 262 slots in default QEMU configuration.

Igor Mammedov (2):
  vhost: extend memory regions allocation to vmalloc
  vhost: add max_mem_regions module parameter
