Which might have been already merged - I'll check tomorrow... - Various misc stuff all over the place - A few block bits which I never got around to sending to Jens - relatively minor things. - MAINTAINERS maintenance - A small number of lib/ updates - checkpatch updates - epoll - firmware/dmi-scan - Some kprobes work for S390 - drivers/rtc updates - hfsplus feature work - vmcore feature work - rbtree upgrades - AOE updates - pktcdvd cleanups - PPS - memstick - w1 - New "inittmpfs" feature, which does the obvious - More IPC work from Davidlohr. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (303 commits) lz4: fix compression/decompression signedness mismatch ipc: drop ipc_lock_check ipc, shm: drop shm_lock_check ipc: drop ipc_lock_by_ptr ipc, shm: guard against non-existant vma in shmdt(2) ipc: document general ipc locking scheme ipc,msg: drop msg_unlock ipc: rename ids->rw_mutex ipc,shm: shorten critical region for shmat ipc,shm: cleanup do_shmat pasta ipc,shm: shorten critical region for shmctl ipc,shm: make shmctl_nolock lockless ipc,shm: introduce shmctl_nolock ipc: drop ipcctl_pre_down ipc,shm: shorten critical region in shmctl_down ipc,shm: introduce lockless functions to obtain the ipc object initmpfs: use initramfs if rootfstype= or root= specified initmpfs: make rootfs use tmpfs when CONFIG_TMPFS enabled initmpfs: move rootfs code from fs/ramfs/ to init/ initmpfs: move bdi setup from init_rootfs to init_ramfs ...
| * drivers/w1/masters/mxc_w1.c: remove unnecessary platform_set_drvdata()Jingoo Han2013-09-121-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The driver core clears the driver data to NULL after device_release or on probe failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based partially on MS standard spec quotes from Alex Dubov. As any code that works with user data this driver isn't recommended to use to write cards that contain valuable data. It tries its best though to avoid data corruption and possible damage to the card. Tested on MS DUO 64 MB card on Ricoh R592 card reader.

| * aoe: create and destroy debugfs directory for aoeEd Cashin2013-09-121-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This series adds the debugging information that the coraid.com-distributed aoe driver exports via sysfs, but instead of sysfs, it uses debugfs. With these patches applied, even without AoE targets on the network, KEDR reports new possible memory leaks, but these are from callers outside the aoe driver that have used aoe_devnode to get the name of the character devices through the aoe_class->devnode callback, and I believe they're responsible for freeing that memory. This patch: Create and destroy the debugfs directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the composition of devm_request_mem_region and devm_ioremap to a single call to devm_ioremap_resource. The associated call to platform_get_resource is also simplified and moved next to the new call to devm_ioremap_resource. This was done using a combination of the semantic patches devm_ioremap_resource.cocci and devm_request_and_ioremap.cocci, found in the scripts/coccinelle/api directory. In rtc-lpc32xx.c and rtc-mv.c, the local variable size is no longer needed. In rtc-ds1511.c the size field of the local structure is not useful any more, and is deleted.

| * drivers/rtc/rtc-hid-sensor-time.c: add module alias to let the module load ↵Alexander Holler2013-09-121-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | automatically In order to get the module automatically loaded by hotplug mechanisms a MODULE_DEVICE_TABLE is needed. Therefore add one. This makes it also possible to use a module name other than HID-SENSOR-2000a0 which isn't very descriptive in kernel messages.

| * firmware/dmi_scan: drop OOM messagesJean Delvare2013-09-121-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Joe Perches: OOM messages generally aren't useful. dmi_alloc is either a trivial front-end to kzalloc, and kzalloc already does a dump_stack() when OOM, or for x86, dmi_alloc uses extend_brk which BUGs when unsuccessful. So we can remove all 6 such log messages in the dmi_scan driver, to shrink the binary size (by 528 bytes on x86_64.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This comment predates the introduction of early_ioremap. Since then the missing calls to dmi_iounmap have been added by Ingo and Yinghai in commits 0d64484f7ea1 ("x86: fix DMI ioremap leak") and 3212bff370c2 ("x86: left over fix for leak of early_ioremp in dmi_scan") . That was over 5 years ago so it is about time to drop this now misleading comment.

| * cciss: set max scatter gather entries to 32 on P600Mike Miller2013-09-121-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At one time we used to set the maximum number of scatter gather elements on all Smart Array controllers to 32. At some point in time the firmware began to write the "appropriate" value for each controller into the config table. The cciss driver would then read that and set h->maxsgentries. h->maxsgentries = readl(&(h->cfgtable->MaxSGElements); On the P600 that value is 544. Under some workloads a significant performance reduction may result. This patch forces the P600 to use only 32 scatter gather elements. Other controllers are not affected.
