[PATCH] use a slab cache for pte_chains
Patch from Bill Irwin.
It removes the custom pte_chain allocator in mm/rmap.c and replaces it
with a slab cache.
"This patch
(1) eliminates the pte_chain_freelist_lock and all contention on it
(2) gives the VM the ability to recover unused pte_chain pages
Anton Blanchard has reported (1) from prior incarnations of this patch.
Craig Kulesa has reported (2) in combination with slab-on-LRU patches.
I've left OOM detection out of this patch entirely as upcoming patches
will do real OOM handling for pte_chains and all the code changed anyway."
