Andrew, Mel,

This struct page stuffing is taking a lot of time to work out and _might_ be
fraught with peril when memmap peekers are considered.

What do you think about just storing the zbud page metadata inline in the
memory page in the first zbud page chunk?

Mel, this kinda hurts you plans for making NCHUNKS = 2, since there would
only be one chunk available for storage and would make zbud useless.

Just a way to sidestep this whole issue.  What do you think?

Seth
