  When running as a guest operating system, the FreeBSD kernel must assume
  that the virtual machine monitor has enabled machine check exceptions.
  Unfortunately, on AMD Family 10h processors the machine check hardware
  has a bug (Erratum 383) that can result in a false machine check exception
  when a superpage promotion occurs.  Thus, I am disabling superpage
  promotion when the FreeBSD kernel is running as a guest operating system
  on an AMD Family 10h processor.
