Xen devel - Aug 2008 - [PATCH]ioemu-remote&ioemu: Fix unmapping issue on hot-removing.

This patch fixes unmapping issue on hot-removing.
I believe my patch and Cui''s patch together fix bug #1316 .
> 1. hot-plug attaching VT-d NIC to guest failed.

After applying this patch, following messages will disappear.

qemu-dm''s message:
pt_unregister_regions: Error: remove old io mapping failed!

Hypervisor''s messages:
(XEN) p2m.c:1172:d0 clear_mmio_p2m_entry: gfn_to_mfn failed! gfn=000fffff
(XEN) domctl.c:820:d0 ioport_map:invalid:gport=ffffffff mport=3000 nr_ports=40

Thanks,

The patch I had sent was applied to xen-unstable.hg (18344: 0cf244daf3c4).

I''d like you to apply the patch to ioemu-remote too.
