x86, x2apic: enable fault handling for intr-remapping
Impact: interface augmentation (not yet used) Enable fault handling flow for intr-remapping aswell. Fault handling code now shared by both dma-remapping and intr-remapping. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
