SVN rev 213226 on 2010-09-27 19:36:15Z by jhb
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.
