SubjectRe: Confusions with reserve_early, reserve_bootmem, e820, efi, ... on x86_64

Reserving EBDA with EFI is fine by what little I know.

But the current code doesn't like it -- if the EFI memmap range is inside
the EBDA range, then the reserve_early() routine panics with:

"Overlapping early reservations"

Something needs tweaking here somehow ... and I'm not the one to know what.

I won't rest till it's the best ...
