Binary files 2.6.5-rc2-aa4/anon-vma.gz and 2.6.5-rc2-aa5/anon-vma.gz differ Add bugcheck for page->mapcount == 0 in alloc/free page paths (just in case). Convert BUG_ON to WARN_ON in page_remove_rmap and added a WARN_ON(page->mapcount) in remove_from_page_cache, to try to trap the case of pages being removed from pagecache while they still had some mapping. Fix ppc (patch was superflous apparently, so backed out, only ppc64 required fixing). Binary files 2.6.5-rc2-aa4/prio-tree.gz and 2.6.5-rc2-aa5/prio-tree.gz differ Fixup nonlinear swapout from Rajesh Venkatasubramanian. Fixed a bugcheck after a split_vma of a MAP_PRIVATE with some anon page on it.
