Linus Torvalds 3c81bdd9e7 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.
