Log Message:
Merge from yamt-pagecache: use radixtree for page lookup.
rbtree page lookup was introduced during the NetBSD 5.0 development cycle to
bypass lock contention problems with the (then) global page hash, and was a
temporary solution to allow us to make progress.radixtree is the intended
replacement.
Ok yamt@.
