find_memory - setup memory map

Walk the EFI memory map and find usable memory for the system, taking into account reserved areas.

find_memory - walk the EFI memory map and setup the bootmem allocator

Called early in boot to setup the bootmem allocator, and to allocate the per-cpu and per-node structures.
