  Log:
  Disable interrupts after using pmap_enter() to add the identity mapping.
  Since pmap_enter() calls pmap_invalidate_page(), which needs interrupts
  enabled in the SMP case, we defer the disable to right before saving the
  register context.  This has been incorrect for about a year but caused no
  real problems because the identity page never actually replaces a previously
  mapped page and suspend/resume on SMP systems has been uncommon.
