  x86: cpu_debug remove execute permission
  x86: smarten /proc/interrupts output for new counters
  x86: DMI match for the Dell DXP061 as it needs BIOS reboot
  x86: make 64 bit to use default_inquire_remote_apic
  x86, setup: un-resequence mode setting for VGA 80x34 and 80x60 modes
  x86, intel-iommu: fix X2APIC && !ACPI build failure

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.
