[PATCH 00/21] mm: page fault scalability nearer

[Hugh Dickins <hugh@veritas.com>]

Here comes the second batch of my page fault scalability patches.
It starts off with a few small adjustments, takes a detour around
update_mem_hiwater in 06/21, then really gets under way with 09/21.

It ends with almost all of the changes complete in the common core, but
still using page_table_lock unscalably.  Scattered changes to arch files,
nothing major, needed before finally splitting the lock in the third batch.

This batch is against 2.6.14-rc2-mm2 plus Nick's core remove PageReserved.
18/21 is a small fix to that patch, you may want to move it down there.

Hugh
