Name:Copy the BIOS E820 map into a safe place.* Sanity-check it while we're at it..* If we're lucky and live on a modern system, the setup code* will have given us a memory map that we can use to properly* set up memory. If we aren't, we'll fake a memory map.
Proto:static int __init append_e820_table(struct boot_e820_entry *entries, unsigned int nr_entries)
Type:int
