[Xen-devel] [PATCH v14 0/3] iommu: add rmrr Xen command line option



Add Xen command line option rmrr to specify RMRR regions that are not
defined in ACPI thus causing IO Page Faults and prevent dom0 from booting
if "iommu=dom0-strict" option is specified on the Xen command line.
These additional regions will be added to the list of RMRR regions parsed
from ACPI.

Changes in v14:
 - Implement Jan's feedback.
   Rename some #defines and take care of boundary conditions.

Changes in v13:
 - Implement feedback from Kevin Tian.
