[PATCH 0/6] gnttab: add per-domain controls

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The first two patches of this series allows setting the preisoutly host
wide command line `gnttab` option on a per domain basis. That means
selecting the max allowed grant table version and whether transitive
grants are allowed.

The last 4 patches attempt to implement support for creating guests
without grant table support at all. This requires some changes to
xenstore in order to map shared ring using foreign memory instead of
grant table.

Note that patch 5 will break the save format for xenstore records, and
should not be applied.

Thanks, Roger.
