vhost: move memory pointer to VQs (2014-06-09 16:21:07 +0300)
----------------------------------------------------------------
vhost: infrastructure changes for 3.16
This reworks vhost core dropping unnecessary RCU uses in favor of VQ mutexes
which are used on fast path anyway. This fixes worst-case latency for users
which change the memory mappings a lot.
Memory allocation for vhost-net now supports fallback on vmalloc (same as for
vhost-scsi) this makes it possible to create the device on systems where memory
is very fragmented, with slightly lower performance.
