---help---
This enables x2apic support on CPUs that have this feature.
This allows 32-bit apic IDs (so it can support very large systems),
and accesses the local apic via MSRs not via mmio.
- ( On certain CPU models you may need to enable INTR_REMAP too,
- to get functional x2apic mode. )
-
If you don't know what to do here, say N.
