- introduce dump_page() to print the page info for debugging some error condition. - convert three mm users: bad_page(), print_bad_pte() and memory offline failure. - print an extra field: the symbolic names of page->flags Example dump_page() output: [ 157.521694] page:ffffea0000a7cba8 count:2 mapcount:1 mapping:ffff88001c901791 index:0x147 [ 157.525570] page flags: 0x100000000100068(uptodate|lru|active|swapbacked) Signed-off-by:

The few lines below the kfree of hdr_buf may go to the label err_free which will also free hdr_buf. The most straightforward solution seems to be to just move the kfree of hdr_buf after these gotos. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier E; expression E1; iterator I; statement S; @@ *kfree(E); ... when != E = E1 when != I(E,...) S when != &E *kfree(E); // </smpl> Signed-off-by:

__zone_pcp_update() iterates over NR_CPUS instead of limiting the access to the possible cpus. This might result in access to uninitialized areas as the per cpu allocator only populates the per cpu memory for possible cpus. This problem was created as a result of the dynamic allocation of pagesets from percpu memory that went in during the merge window - commit 99dcc3e5 ("this_cpu: Page allocator conversion").

Commit 34e55232 ("mm: avoid false sharing of mm_counter") added sync_mm_rss() for syncing loosely accounted rss counters. It's for CONFIG_MMU but sync_mm_rss is called even in NOMMU enviroment (kerne/exit.c, fs/exec.c). Above commit doesn't handle it well. This patch changes SPLIT_RSS_COUNTING depends on SPLIT_PTLOCKS && CONFIG_MMU And for avoid unnecessary function calls, sync_mm_rss changed to be inlined noop function in header file. Reported-by:
