x86, dmar: use atomic allocations for QI and Intr-remapping init
Impact: invalid use of GFP_KERNEL in interrupt context Queued invalidation and interrupt-remapping will get initialized with interrupts disabled (while enabling interrupt-remapping). So use GFP_ATOMIC instead of GFP_KERNEL for memory alloacations. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
