[RFC PATCH 0/2] xen/gnttab: reduce size of struct active_grant_entry

[Juergen Gross <jgross@xxxxxxxx>]

While looking at the grant table code I thought it should be possible
to have a smaller struct active_grant_entry. This approach should only
hit transitive grants with some negative performance effect, "normal"
grants should be not affected.

I'm not sure that the domid_to_domain() helper is something we really
want, though, so I'm sending out the series as RFC.
