I'm updating this patch for recent -CURRENT. Any comments I can incorporate?

I've committed a new mechanism for relocating pages to HEAD in r292469 that addresses the contiguous memory allocation problem without resorting to dirty page laundering. Similarly, this new mechanism achieves the goal of not relying on PG_CACHED pages. This patch can be abandoned.

Kip, this change should also be closed out.
