I synced up to next-20130213 and the problem is fixed.  :)  ...that
label doesn't exactly boot but the problems are unrelated to this
problem now (there are problems with the OF conversions to raw
spinlocks)...

I haven't done any review of this code (I'm assuming that Olof already
looked it over and Samsung engineers will give it a thorough review),
but it's definitely tested.  :)

Thanks!
