Merge branch 'akpm' (aka "Andrew's patch-bomb")
Andrew elucidates: - First installmeant of MM. We have a HUGE number of MM patches this time. It's crazy. - MAINTAINERS updates - backlight updates - leds - checkpatch updates - misc ELF stuff - rtc updates - reiserfs - procfs - some misc other bits * akpm: (124 commits) user namespace: make signal.c respect user namespaces workqueue: make alloc_workqueue() take printf fmt and args for name procfs: add hidepid= and gid= mount options procfs: parse mount options procfs: introduce the /proc/<pid>/map_files/ directory procfs: make proc_get_link to use dentry instead of inode signal: add block_sigmask() for adding sigmask to current->blocked sparc: make SA_NOMASK a synonym of SA_NODEFER reiserfs: don't lock root inode searching reiserfs: don't lock journal_init() reiserfs: delay reiserfs lock until journal initialization reiserfs: delete comments referring to the BKL drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-range drivers/rtc/rtc-twl.c: add DT support for RTC inside twl4030/twl6030 drivers/rtc/: remove redundant spi driver bus initialization drivers/rtc/rtc-jz4740.c: make jz4740_rtc_driver static drivers/rtc/rtc-mc13xxx.c: make mc13xxx_rtc_idtable static rtc: convert drivers/rtc/* to use module_platform_driver() drivers/rtc/rtc-wm831x.c: convert to devm_kzalloc() drivers/rtc/rtc-wm831x.c: remove unused period IRQ handler ...

+/*
+ * leds-tca6507
+ *
+ * The TCA6507 is a programmable LED controller that can drive 7
+ * separate lines either by holding them low, or by pulsing them
+ * with modulated width.
+ * The modulation can be varied in a simple pattern to produce a blink or
+ * double-blink.
+ *
+ * This driver can configure each line either as a 'GPIO' which is out-only
+ * (no pull-up) or as an LED with variable brightness and hardware-assisted
+ * blinking.
+ *
+ * Apart from OFF and ON there are three programmable brightness levels which
+ * can be programmed from 0 to 15 and indicate how many 500usec intervals in
+ * each 8msec that the led is 'on'. The levels are named MASTER, BANK0 and
+ * BANK1.
+ *
+ * There are two different blink rates that can be programmed, each with
+ * separate time for rise, on, fall, off and second-off. Thus if 3 or more
+ * different non-trivial rates are required, software must be used for the extra
+ * rates. The two different blink rates must align with the two levels BANK0 and
+ * BANK1.
+ * This driver does not support double-blink so 'second-off' always matches
+ * 'off'.
+ *
+ * Only 16 different times can be programmed in a roughly logarithmic scale from
+ * 64ms to 16320ms. To be precise the possible times are:
+ * 0, 64, 128, 192, 256, 384, 512, 768,
+ * 1024, 1536, 2048, 3072, 4096, 5760, 8128, 16320
+ *
+ * Times that cannot be closely matched with these must be
+ * handled in software. This driver allows 12.5% error in matching.
+ *
+ * This driver does not allow rise/fall rates to be set explicitly. When trying
+ * to match a given 'on' or 'off' period, an appropriate pair of 'change' and
+ * 'hold' times are chosen to get a close match. If the target delay is even,
+ * the 'change' number will be the smaller; if odd, the 'hold' number will be
+ * the smaller.
+
+ * Choosing pairs of delays with 12.5% errors allows us to match delays in the
+ * ranges: 56-72, 112-144, 168-216, 224-27504, 28560-36720.
+ * 26% of the achievable sums can be matched by multiple pairings. For example
+ * 1536 == 1536+0, 1024+512, or 768+768. This driver will always choose the
+ * pairing with the least maximum - 768+768 in this case. Other pairings are
+ * not available.
+ *
+ * Access to the 3 levels and 2 blinks are on a first-come, first-served basis.
+ * Access can be shared by multiple leds if they have the same level and
+ * either same blink rates, or some don't blink.
+ * When a led changes, it relinquishes access and tries again, so it might
+ * lose access to hardware blink.
+ * If a blink engine cannot be allocated, software blink is used.
+ * If the desired brightness cannot be allocated, the closest available non-zero
+ * brightness is used. As 'full' is always available, the worst case would be
+ * to have two different blink rates at '1', with Max at '2', then other leds
+ * will have to choose between '2' and '16'. Hopefully this is not likely.
+ *
+ * Each bank (BANK0 and BANK1) has two usage counts - LEDs using the brightness
+ * and LEDs using the blink. It can only be reprogrammed when the appropriate
+ * counter is zero. The MASTER level has a single usage count.
+ *
+ * Each Led has programmable 'on' and 'off' time as milliseconds. With each
+ * there is a flag saying if it was explicitly requested or defaulted.
+ * Similarly the banks know if each time was explicit or a default. Defaults
+ * are permitted to be changed freely - they are not recognised when matching.
+ *
+ *
+ * An led-tca6507 device must be provided with platform data. This data
+ * lists for each output: the name, default trigger, and whether the signal
+ * is being used as a GPiO rather than an led. 'struct led_plaform_data'
+ * is used for this. If 'name' is NULL, the output isn't used. If 'flags'
+ * is TCA6507_MAKE_CPIO, the output is a GPO.
+ * The "struct led_platform_data" can be embedded in a
+ * "struct tca6507_platform_data" which adds a 'gpio_base' for the GPiOs,
+ * and a 'setup' callback which is called once the GPiOs are available.
