[PATCH v12 0/3] iommu: add rmrr Xen command line option

[elena.ufimtseva@oracle.com]

From: Elena Ufimtseva <elena.ufimtseva@oracle.com>

Sending v12 with mostly cosmetic fixes from Jan's review on v11.

Add Xen command line option rmrr to specify RMRR regions that are not defined
in ACPI thus causing IO Page Fault while booting dom0 in PVH mode.
These additional regions will be added to the list of RMRR regions parsed from ACPI.

Changes in v11:
 - changed macro to print extra RMRR ranges and added argument macro;
 - fixed the overlapping check if condition error;
 - fixed the loop exit condition when checking pfn in RMRR region;

Elena Ufimtseva (3):
  iommu VT-d: separate rmrr addition function
  pci: add wrapper for parse_pci
  iommu: add rmrr Xen command line option for extra rmrrs
