lib: Add support for LZ4-compressed kernel

Date	Tue, 26 Feb 2013 15:24:28 +0900

This patch adds support for extracting LZ4-compressed kernel images,
as well as LZ4-compressed ramdisk images in the kernel boot process.

This depends on the patch below
decompressor: Add LZ4 decompressor module

Signed-off-by: Kyungsik Lee <kyungsik.lee@lge.com>

v2:
- Clean up code
- Use lz4_decompress() for LZ4-compressed kernel during boot-process

arm: Add support for LZ4-compressed kernel

Date	Tue, 26 Feb 2013 15:24:29 +0900

This patch integrates the LZ4 decompression code to the arm pre-boot code.
And it depends on two patchs below

lib: Add lz4 compressor module

From	Chanho Min <>

This patch adds support for LZ4 compression in the Linux Kernel.
LZ4 Compression APIs for kernel are based on LZ4 implementation
by Yann Collet and changed with kernel coding style.

LZ4 homepage : http://fastcompression.blogspot.com/p/lz4.html
LZ4 source repository : http://code.google.com/p/lz4/
svn revision : r90

Two APIs are added:
lz4_compress() support basic lz4 compression whereas lz4hc_compress() support
high compression or CPU performance get lower but compression ratio get higher.
Also, we require the pre-allocated working memory with the defined size and
destination buffer must be allocated with the size of lz4_compressbound.

LZ4: compression/decompression signedness mismatch (v2)

LZ4 compression and decompression functions require different
in signedness input/output parameters: unsigned char for
compression and signed char for decompression.

Change decompression API to require "(const) unsigned char *".

v2: minor coding style fix.

sound control: kitkat compatibility fix up
sound control: remove taiko_read

taiko_read could sometimes causes a kernel panic, however it is not a necessary function so we simply remove everything associated.
also remove unused poweramp register controls and only retain headphone_pa_gain_show for compatibility.
mdnie lite control: initial control interface (version 1.3)

Version 1.3: updated sysfs interface
Version 1.2: fixed compatibility with samsung NA6 (kitkat) source.

sysfs controls for RGBCMYWK channel and "sharpen" effect:
[/sys/class/mdnie/mdnie/*]
(* = red, green, blue, cyan, magenta, yellow, white, black, sharpen)

override for all samsung modes and profiles:
[echo 1 > /sys/class/mdnie/mdnie/override]

[echo 255 150 75 > /sys/class/mdnie/mdnie/red]
(255 = red; 150 = green; 75 = blue)

Copy color profile from existing mdnie profile:
(echo x > /sys/class/mdnie/mdnie/copy_mode)

where X equals :
- 0 = Standard
- 1 = Natural
- 2 = Movie

copy gamma curve from existing mdnie profile:
[echo x > /sys/class/mdnie/mdnie/gamma_curve]

where X equals :
- 0 = Movie
- 1 = Dynamic

Idea based on (mDNIe colour and brightness control) by AndreiLux.

 - Allow for customized brightness and delayon / delayoff control by user

 * SysFs interface :

 *
 * /sys/class/sec/led/led_intensity : 0 - 255 (100 = stock)
 *
 *     Set the relative intensity of the LED respecting the userspace's request
 *
 * /sys/class/sec/led/led_speed_on  : 1 - 5 (1 = stock)
 *
 *     Devider for delayon  (1 - 5 times shorter than requested by userspace)
 *
 * /sys/class/sec/led/led_speed_off  : 1 - 5 (1 = stock)
 *
 *     Devider for delayoff (1 - 5 times shorter than requested by userspace)
 *
 * /sys/class/sec/led/led_xctrl_version :

 *     Display the current version of the eXtended ConTRoLs
 *
 * /sys/class/sec/led/led_xctrl_info :
 *
 *     Display the current settings in human readable format

timekeeping: Fix time moving backwards

Changed the calculation logic that sometimes calculates
the time wrong.

Sometimes there is an overflow when the tv_nsec field in
the timespec structure is being added since it is 32-bit.

To resolve this issue nsec variable is being added first
so that the addition is performed in 64 bit signed format.

cpufreq: force cpuN policy to match cpu0 when changing freq or gov
cpufreq: Manage only online cpus

cpufreq core doesn't manage offline cpus and if driver->init() has returned
mask including offline cpus, it may result in unwanted behavior by cpufreq core
or governors.

We need to get only online cpus in this mask. There are two places to fix this
mask, cpufreq core and cpufreq driver. It makes sense to do this at common place
and hence is done in core.
