AMD,IOMMU: Clean up old entries in remapping tables when creating new one
When changing the affinity of an IRQ associated with a passed
through PCI device, clear previous mapping.
This is XSA-36 / CVE-2013-0153.
Signed-off-by: Jan Beulich <jbeulich@suse.com>
In addition, because some BIOSes may incorrectly program IVRS
entries for IOAPIC try to check for entry's consistency. Specifically,
if conflicting entries are found disable IOMMU if per-device
remapping table is used. If entries refer to bogus IOAPIC IDs
disable IOMMU unconditionally
