[PATCH] Missing memory barrier in pte_chain_unlock
On a ppc64 machine running 2.5.28 we were hitting this BUG in
__free_pages_ok:
BUG_ON(page->pte.chain != NULL);
In pte_chain_lock we use test_and_set_bit which implies a memory
barrier. In pte_chain_unlock we use clear_bit which has no memory
barriers so we need to add one.
