  SVN rev 197663 on 2009-10-01 12:52:48Z by kib
  
  As a workaround, for Intel CPUs, do not use CLFLUSH in
  pmap_invalidate_cache_range() when self-snoop is apparently not reported
  in cpu features. We get a reserved trap when clflushing APIC registers
  window.
  
  XEN in full system virtualization mode removes self-snoop from CPU
  features, making this a problem.
