Ahh, ok.  I was under the assumption that an entire patchset would be
applied en-mass and only divided up by bi-sect debugging...?

The second patchset (cpumask) is highly incremental and I did it like
this to show memory gains (or losses).  I tossed a few patches that
didn't have any overall goodness (and have a few more to help with
the memory footprint or performance in the queue.)

Thanks,
Mike
