dda367ac06 rtc/ab8500: add calibration attribute to AB8500 RTC
The rtc_calibration attribute allows user-space to get and set the
AB8500's RtcCalibration register.  The AB8500 will then use the value in
this register to compensate for RTC drift every 60 seconds.

012e52e15e drivers/rtc/rtc-ab8500.c: change msleep() to usleep_range()
The resolution of msleep is related to HZ, so with HZ set to 100 any
msleep of less than 10ms will become ~10ms.  This is not what we want.
Use the hrtimer-based usleep_range() and allow for some slack in the
non-critical path so we have more control of what is happening here.

e39f560239 fs: binfmt_elf: create Kconfig variable for PIE randomization
Randomization of PIE load address is hard coded in binfmt_elf.c for X86
and ARM.  Create a new Kconfig variable
(CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE) for this and use it instead.  Thus
architecture specific policy is pushed out of the generic binfmt_elf.c and
into the architecture Kconfig files.

X86 and ARM Kconfigs are modified to select the new variable so there is
no change in behavior.  A follow on patch will select it for MIPS too.

bfcb2cc798 checkpatch: catch all occurences of type and cast spacing errors per line
Fix up type and cast spacing checks such that all occurences on a line are
examined and reported.  For example the line below has a valid cast and a
bad type, but currently we check the cast first which is good and stop:

    u16* bar = (u16 *)baz;

We will also only report one of the errors in this example:

    u16* bar = (u16*)bad;

Move to iterating across all casts and all types, reporting any failure.

d7c76ba7e5 checkpatch: improve memset and min/max with cast checking
Improve the checking of arguments to memset and min/max tests.

Move the checking of min/max to statement blocks instead of single line.
Change $Constant to allow any case type 0x initiator and trailing ul
specifier.  Add $FuncArg type as any function argument with or without a
cast.  Print the whole statement when showing memset or min/max messages.
Improve the memset with 0 as 3rd argument error message.

There are still weaknesses in the $FuncArg and $Constant code as arbitrary
parentheses and negative signs are not generically supported.

f74bd1942e checkpatch: correctly track the end of preprocessor commands in context
When looking for a statement we currently run on through preprocessor
commands.  This means that a header file with just definitions is parsed
over and over again combining all of the lines from the current line to
the end of file leading to severe performance issues.

Fix up context accumulation to track preprocessor commands and stop when
reaching the end of them.  At the same time vastly simplify the #define
handling.

96b62067f9 btree: export btree_get_prev() so modules can use btree_for_each
The btree_for_each API is implemented with macros that internally call
btree_get_prev(), so if btree_get_prev() isn't exported then modules fail
to link if they try to use one of the btree_for_each macros.  Since the
rest of the btree API is exported, we should keep things orthogonal and
make this work too.

66655760bf backlight: use kstrtoul()
The usage of simple_strtoul() or strict_strtoul() is not preferred.  Thus,
kstrtoul should be used.

This patch also fixes checkpatch error as follows:
ERROR: space required after that ',' (ctx:VxV)

b148a27294 backlight/ld9040.c: regulator control in the driver
This patch supports regulator power control in the driver.  Current ld9040
driver was controlled power on/off sequence by callback function in the
board file.  But, by doing this, there's no need to register lcd power
on/off callback function in the board file.

81178e0216 backlight: convert drivers/video/backlight/* to use module_platform_driver()
Convert the drivers in drivers/video/backlight/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

3ed0c15fd1 backlight: remove ADX backlight device support
Support for the Avionic Design Xanthos backlight device got added in
commit 3b96ea9ef8 ("backlight: Add support for the Avionic Design Xanthos
backlight device.").  That support depends on ARCH_PXA_ADX.  The code that
should have provided that Kconfig symbol never got submitted.  It has
never been possible to even build this driver.  Remove it.
