Russell,
I've been trying to get these in for a while now. They're just Kconfig
changes that allow MSM to use SMP. One of the patch does have a slight
clean up where it moves the "\" out one space under "config SMP". I
think that was the product of some feedback I received.
Please pull, or let me know if you want them done differently.
Daniel
