  This patches fix a NMI problem I was seeing when running xenoprof on
SMP guests.
  The machine used to auto reboot if an NMI was received in a critical
time window when
  context switching domains. There is a small time window when the GDT
may become unmapped
  (after CR3 is updated and before setting GDTR with the new GDT during
a domain context
  switch. If an NMI is received during this time window a triple fault
is triggered causing
  the machine to auto reboot. This patch fix this problem. Please,

Good catch. That's an evil bug...
