[RFC] virtio-pmem: PMEM device spec
f52ae55 
This patch proposes a virtio specification for new
virtio pmem device. Virtio pmem is a paravirtualized
device which allows the guest to bypass page cache.
Previous posting of kernel driver is [1] and Qemu
device is [2]. Specification has introduction of
virtio pmem device with other implementation details.

I have also listed concerns with page cache side channel
attacks in previous kernel driver posting [1] and
possible countermeasures based on discussion [4].
I have also created an virtio-spec issue [5] for this.

Request to provide feedback on device specification.
