Changes are isolated to sanitize_e820_map().

(patch is against linux-2.4.3-ac3)

This change informs the user when overlaping memory regions have been
found in their e820 map.  If overlaps were found, it displays the 
original mapping and then creates an adjusted map (w/o overlaps).  If 
no overlaps were found, it leaves the original bios-provided map alone.  
Formatting changes were also made so source fits w/in 80 columns.

Hope it helps,

Brian
