Alex Nixon 7347b4082e xen: Allow unprivileged Xen domains to create iomap pages ... PV DomU domains are allowed to map hardware MFNs for PCI passthrough, but are not generally allowed to map raw machine pages. In particular, various pieces of code try to map DMI and ACPI tables in the ISA ROM range. We disallow _PAGE_IOMAP for those mappings, so that they are redirected to a set of local zeroed pages we reserve for that purpose. [ Impact: prevent passthrough of ISA space, as we only allow PCI ] Signed-off-by: Alex Nixon <alex.nixon@citrix.com> Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>		2010-06-07 14:33:13 -04:00
