  SVN rev 216843 on 2010-12-31 17:39:31Z by cperciva
  
  Make i386_set_ldt work on i386/XEN, step 1/5.
  
  Lock the vm page queue mutex around calls to pte_store.  As with many other
  uses of the vm page queue mutex in i386/xen/pmap.c, this is bogus and needs
  to be replaced at some future date by a spin lock dedicated to protecting
  the queue of pending xen page mapping hypervisor calls.  (But for now, bogus
  locking is better than a panic.)
