[Xen-devel] [PATCH v3] Userspace grant communication

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

Rebased on top of Stefano's 2.6.37 gntdev patches; included suggestions
from the v2 patch queue. HVM mapping is now much cleaner, since pages
with real GFNs are available. Multicall API didn't make it in, because
the actual hypercall is within a function that I'm not sure should be
changed to multicall in all instances, and I haven't had a chance to
figure out how to use it despite this.

[PATCH 6/7] xen-gntdev: Support mapping in HVM domains
