x86, setup: preemptively save/restore edi and ebp around INT 15 E820
Impact: BIOS bugproofing Since there are BIOSes known to clobber %ebx and %esi for INT 15 E820, assume there is something out there clobbering %edi and/or %ebp too, and don't wait for it to fail. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
