Merge branch 'akpm' (patches from Andrew Morton)
Merge first patch-bomb from Andrew Morton: - Some pidns/fork/exec tweaks - OCFS2 updates - Most of MM - there remain quite a few memcg parts which depend on pending core cgroups changes. 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 ...
