[Xen-devel] first attempt of pvscai backend driver port to pvops

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

Attached is my first attempt at getting the backend pvscsi driver
(scsiback) working under the latest pvops kernel. I have tested it with
the scsi frontend driver in gplpv, and have restored about 20GB of data
from a HP LTO3 tape drive successfully, so it appears to be working
fine.

There are quite a few changes compared to the version in 2.6.18. The
main change is that I get the vaddr for each sg element and use the
regular dma calls to make it work instead of all the magic that the
2.6.18 version used to use that isn't exported anymore.

I created a new branch in a local git repo, what git magic do I need to
weave to make the patch look a bit neater?

Thanks

James
