I noticed that some of the other architectures have started using the
<linux/memblock.h> APIs for memory setup.  Do you think this would be
useful on MIPS, as part of a larger refactoring of bootmem_init() ?

What I liked about Michael's fix was that it is simple and
straightforward enough to meet the stable tree criteria.  Long term it
would probably be a good idea to clean up the memory init code and get
rid of the cut&paste "for" loops.
