  SVN rev 213746 on 2010-10-12 19:28:33Z by jhb
  
  MFC 213226:
  Rewrite the i386 memory probe:
  - Check for SMAP data from the loader first.  If it exists, don't bother
    doing any VM86 calls at all.  This will be more friendly for non-BIOS
    boot environments such as EFI, etc.
  - Move the base memory setup into a new basemem_setup() routine instead
    of duplicating it.
  - Simplify the XEN case by removing all of the VM86/SMAP parsing code rather
    than just jumping over it.
  - Adjust some comments to better explain the code flow.
