Subject: pvh dom0: allow get_pg_owner for translated domains if pvh
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~4937
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=594e6fd413d646521cc29b38bc89f897b4570977;p=xen.git

pvh dom0: allow get_pg_owner for translated domains if pvh

When creating a PV guest, toolstack on pvh dom0 will do_mmuext_op
to pin guest tables. do_mmuext_op calls get_pg_owner, which must allow
foreign mappings for pvh.
