kernel - Implement KVABIO API in TMPFS
* TMPFS now fully supports the KVABIO API. This removes nearly all
IPIs from buffer cache operations related to TMPFS.
* In synth tests on 32-way and 48-way servers, the number of IPIs/cpu/sec
drops from 5000-12000 down to 200-1000. Needless to say, this is a
huge win, particularly on VMs.
