2011-05-19list: remove prefetching from regular list iteratorsLinus Torvalds2-18/+14
This is removes the use of software prefetching from the regular list iterators. We don't want it. If you do want to prefetch in some iterator of yours, go right ahead. Just don't expect the iterator to do it, since normally the downsides are bigger than the upsides. It also replaces <linux/prefetch.h> with <linux/const.h>, because the use of LIST_POISON ends up needing it. <linux/poison.h> is sadly not self-contained, and including prefetch.h just happened to hide that. Suggested by David Miller (networking has a lot of regular lists that are often empty or a single entry, and prefetching is not going to do anything but add useless instructions). Acked-by: Ingo Molnar <mingo@elte.hu> Acked-by: David S. Miller <davem@davemloft.net> Cc: linux-arch@vger.kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-05-19hlist: remove software prefetching in hlist iteratorsLinus Torvalds2-10/+9
They not only increase the code footprint, they actually make things slower rather than faster. On internationally acclaimed benchmarks ("make -j16" on an already fully built kernel source tree) the hlist prefetching slows down the build by up to 1%. (Almost all of it comes from hlist_for_each_entry_rcu() as used by avc_has_perm_noaudit(), which is very hot due to all the pathname lookups to see if there is anything to do). The cause seems to be two-fold: - on at least some Intel cores, prefetch(NULL) ends up with some microarchitectural stall due to the TLB miss that it incurs. The hlist case triggers this very commonly, since the NULL pointer is the last entry in the list. - the prefetch appears to cause more D$ activity, probably because it prefetches hash list entries that are never actually used (because we ended the search early due to a hit). Regardless, the numbers clearly say that the implicit prefetching is simply a bad idea. If some _particular_ user of the hlist iterators wants to prefetch the next list entry, they can do so themselves explicitly, rather than depend on all list iterators doing so implicitly.

2011-05-19kmemleak: Initialise kmemleak after debug_objects_mem_init()Catalin Marinas1-1/+1
Kmemleak frees objects via RCU and when CONFIG_DEBUG_OBJECTS_RCU_HEAD is enabled, the RCU callback triggers a call to free_object() in lib/debugobjects.c. Since kmemleak is initialised before debug objects initialisation, it may result in a kernel panic during booting. This patch moves the kmemleak_init() call after debug_objects_mem_init().

2011-05-19kmemleak: Select DEBUG_FS unconditionally in DEBUG_KMEMLEAKCatalin Marinas1-1/+1

2011-05-19kmemleak: Do not return a pointer to an object that kmemleak did not getCatalin Marinas1-2/+5
The kmemleak_seq_next() function tries to get an object (and increment its use count) before returning it. If it could not get the last object during list traversal (because it may have been freed), the function should return NULL rather than a pointer to such object that it did not get.

2011-05-19m68k: bitops - Never step beyond the end of the bitmapGeert Uytterhoeven1-26/+55
find_next bitops on m68k (find_next_zero_bit, find_next_bit, and find_next_bit_le) may cause out of bounds memory access when the bitmap size in bits % 32 != 0 and offset (the bitnumber to start searching at) is very close to the bitmap size. For example, unsigned long bitmap[2] = { 0, 0 }; find_next_bit(bitmap, 63, 62); 1. find_next_bit() tries to find any set bits in bitmap[1], but no bits set. 2. Then find_first_bit(bimap + 2, -1) 3. Unfortunately find_first_bit() takes unsigned int as the size argument. 4. find_first_bit will access bitmap[2~] until it find any set bits. Add missing tests for stepping beyond the end of the bitmap to all find_{first,next}_*() functions, and make sure they never return a value larger than the bitmap size.
