2.4.3-ac10: sanitize_e820_map()

Summary:
print bad BIOS maps (those containing overlaps in memory regions).

Kernel:
linux-2.4.3-ac10

Description:
This change informs the user when overlaping memory regions are found in an e820 memory map. If overlaps are found, the mapping is displayed and then an adjusted map is created (without overlaps). If no overlaps are found, the original mapping is left untouched.
