This is a pretty unfortunate choice of names for this function.  See
mm/bootmem.c.

Other than that, your patch works fine for me; my Indy has 192MB
memory and it's detected properly.  I do get an oops in do_be from
xdm, but I get that without the patch also.

Determined physical RAM map:
 memory: 00001000 @ 00000000 (reserved)
 memory: 00001000 @ 00001000 (reserved)
 memory: 001e1000 @ 08002000 (reserved)
 memory: 0055d000 @ 081e3000 (usable)
 memory: 000c0000 @ 08740000 (ROM data)
 memory: 0b800000 @ 08800000 (usable)

I need to do the same kind of thing for ip32 as the ARC memory
detection has the same shortcoming on that platform.  No sense having
a machine support 1GB memory and only looking for 256MB of it,
especially in a 64-bit kernel.  ARC[S] really does seem to be useless.
