[Xen-devel] [Patch] make MEMZONE_DOM as deafult for xen_create_contiguous_region
Otherwise, dom0 will just be eating away from MEMZONE_DMADOM for every
xen_create_contiguous_region() call, with out ever giving it back. And
as it stands today, there is no point in having
xen_destroy_contiguous_region().
Appended patch will fix this.
