[GIT PULL] virtio: features, fixes

[Michael S. Tsirkin]

There's a single commit here that I tweaked since linux-next - the
change is in printk format string which I consider trivial enough not
force wait for more testing. A couple of hashes are different from
what's in linux-next though.  I also upgraded the machine I used to sign
the tag (didn't change the key) - hope the signature is still ok. If not
pls let me know!

The following changes since commit 3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162:
