[PATCH v4 00/42] linux: towards virtio-1 guest support

[Michael S. Tsirkin]

Based on patches by Cornelia and others, but
with an API that should allow better static checking of code,
slightly more concervative changes in vring and drivers,
and compatibility for existing drivers so that
this series can be applied before all drivers are converted.

virtio net,blk and scsi drivers have been converted.
They now pass sparse without warnings.

net and blk patches have been tested on s390.
scsi patches pass sparse so they are most likely
ok too, but haven't been through testing yet -
they can be dropped from patchset if necessary.

Please review, and consider for 3.19

Changes since v3:
	- move virtio 1.0 feature bit out of transport bits:
	  for now it's managed by drivers
	- disable virtio 1.0 feature bit explicitly - for transports
	  that don't support it

David, assuming patches are acceptable, I'd like them all to be merged through
virtio or vhost trees.  Could you please ack doing that for net related
patches?
