x2apic/intr-remap: decouple interrupt remapping from x2apic
interrupt remapping must be enabled before enabling x2apic, but interrupt remapping doesn't depend on x2apic, it can be used separately. Enable interrupt remapping in init_dmars even x2apic is not supported. [dwmw2: Update Kconfig accordingly, fix build with INTR_REMAP && !X2APIC] Signed-off-by: Weidong Han <weidong.han@intel.com> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
