New Revision: 210935
URL: http://svn.freebsd.org/changeset/base/210935

Log:
  Add Xen to the list of virtual vendors.  In the non PV (HVM) case this fixes
  the virtualization detection successfully disabling the clflush instruction.
  This fixes insta-panics for XEN hvm users when the hw.clflush_disable
  tunable is -1 or 0 (-1 by default).
