  SVN rev 211891 on 2010-08-27 18:55:24Z by jhb
  
  MFC 210774,210935:
  - Tweak the logic to disable CLFLUSH in virtual environments to work around
    problems with flushing the local APIC register range so that it checks
    vm_guest directly.
  - Add Xen to the list of virtual vendors.  In the non PV (HVM) case this
    fixes the virtualization detection successfully disabling the CLFLUSH
    instruction.
