Merge branch 'akpm' (Andrew's patch-bomb)
Merge second batch of patches from Andrew Morton: - various misc things - core kernel changes to prctl, exit, exec, init, etc. - kernel/watchdog.c updates - get_maintainer - MAINTAINERS - the backlight driver queue - core bitops code cleanups - the led driver queue - some core prio_tree work - checkpatch udpates - largeish crc32 update - a new poll() feature for the v4l guys - the rtc driver queue - fatfs - ptrace - signals - kmod/usermodehelper updates - coredump - procfs updates * emailed from Andrew Morton <akpm@linux-foundation.org>: (141 commits) seq_file: add seq_set_overflow(), seq_overflow() proc-ns: use d_set_d_op() API to set dentry ops in proc_ns_instantiate(). procfs: speed up /proc/pid/stat, statm procfs: add num_to_str() to speed up /proc/stat proc: speed up /proc/stat handling fs/proc/kcore.c: make get_sparsemem_vmemmap_info() static coredump: add VM_NODUMP, MADV_NODUMP, MADV_CLEAR_NODUMP coredump: remove VM_ALWAYSDUMP flag kmod: make __request_module() killable kmod: introduce call_modprobe() helper usermodehelper: ____call_usermodehelper() doesn't need do_exit() usermodehelper: kill umh_wait, renumber UMH_* constants usermodehelper: implement UMH_KILLABLE usermodehelper: introduce umh_complete(sub_info) usermodehelper: use UMH_WAIT_PROC consistently signal: zap_pid_ns_processes: s/SEND_SIG_NOINFO/SEND_SIG_FORCED/ signal: oom_kill_task: use SEND_SIG_FORCED instead of force_sig() signal: cosmetic, s/from_ancestor_ns/force/ in prepare_signal() paths signal: give SEND_SIG_FORCED more power to beat SIGNAL_UNKILLABLE Hexagon: use set_current_blocked() and block_sigmask() ...
