This is clearly one of the inflection points of the series.

To go any farther with this approach, I think it's critical to get a few
acks on this hunk specifically. Well, maybe not formal acked-by's, but
at least _clear_ agreement from at least one of:

	MEMORY MANAGEMENT - PAGE ALLOCATOR
	M:      Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
	M:      Vlastimil Babka <vbabka@xxxxxxx>

... or this approach is dead in the water.
