[Xen-devel] [PATCH]fix xencomm_copy_{from, to}_guest.
fix xencomm_copy_{from, to}_guest.
It should not call paddr_to_maddr() with invalid address.
Originally this issue was found in xen/ia64 xencomm code and
in fact I didn''t test this patch because currently ia64 xencomm forked
from common code. They should be consolidated somehow.

Just quickly tried it out and my js20 blade boots without issue with this patch.
