Merge branch 'akpm' (Andrew's incoming)
Quoth Andrew: - Most of MM. Still waiting for the poweroc guys to get off their butts and review some threaded hugepages patches. - alpha - vfs bits - drivers/misc - a few core kerenl tweaks - printk() features - MAINTAINERS updates - backlight merge - leds merge - various lib/ updates - checkpatch updates * akpm: (127 commits) epoll: fix spurious lockdep warnings checkpatch: add a --strict check for utf-8 in commit logs kernel.h/checkpatch: mark strict_strto<foo> and simple_strto<foo> as obsolete llist-return-whether-list-is-empty-before-adding-in-llist_add-fix wireless: at76c50x: follow rename pack_hex_byte to hex_byte_pack fat: follow rename pack_hex_byte() to hex_byte_pack() security: follow rename pack_hex_byte() to hex_byte_pack() kgdb: follow rename pack_hex_byte() to hex_byte_pack() lib: rename pack_hex_byte() to hex_byte_pack() lib/string.c: fix strim() semantics for strings that have only blanks lib/idr.c: fix comment for ida_get_new_above() lib/percpu_counter.c: enclose hotplug only variables in hotplug ifdef lib/bitmap.c: quiet sparse noise about address space lib/spinlock_debug.c: print owner on spinlock lockup lib/kstrtox: common code between kstrto*() and simple_strto*() functions drivers/leds/leds-lp5521.c: check if reset is successful leds: turn the blink_timer off before starting to blink leds: save the delay values after a successful call to blink_set() drivers/leds/leds-gpio.c: use gpio_get_value_cansleep() when initializing drivers/leds/leds-lm3530.c: add __devexit_p where needed ...
