2010-03-13mm: do not iterate over NR_CPUS in __zone_pcp_update()Thomas Gleixner1-1/+1
__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 99dcc3e5a94ed491fbef402831d8c0bbb267f995 ("this_cpu: Page allocator conversion").

2010-03-13nommu: fix build breakageKAMEZAWA Hiroyuki3-4/+7
Commit 34e55232e59f7b19050267a05ff1226e5cd122a5 ("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.

2010-03-13sdio: recognize io card without powercycleAlbert Herranz3-6/+32
SDIO Simplified Specification V2.00 states that it is strongly recommended that the host executes either a power reset or issues a CMD52 (I/O Reset) to re-initialize an I/O only card or the I/O portion of a combo card. Additionally, the CMD52 must be issued first because it cannot be issued after a CMD0. With this patch the Nintendo Wii SDIO-based WLAN card is detected after a system reset, without requiring a complete system powercycle.

Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys contains a 1 (meaning "This rtc was used to initialize the system clock") even if reading the time at bootup failed. Moreover change error handling in rtc_hctosys() to use goto and so reduce the indention level.

2010-03-13fs: buffer_head: remove kmem_cache constructor to reduce memory usage under slubRichard Kennedy1-11/+2
When using slub, having a kmem_cache constructor forces slub to add a free pointer to the size of the cached object, which can have a significant impact to the number of small objects that can fit into a slab. As buffer_head is relatively small and we can have large numbers of them, removing the constructor is a definite win. On x86_64 removing the constructor gives me 39 objects/slab, 3 more than without the patch. And on x86_32 73 objects/slab, which is 9 more. As alloc_buffer_head() already initializes each new object there is very little difference in actual code run.
