[RFC PATCH 0/4] ARM: EXYNOS4: Use cpuidle common save/restore framework code

[amit.kachhap@linaro.org (Amit Daniel Kachhap)]

These patch adds support for samsung exynos4 platform cpuidle driver to use
the common cpuidle framework submitted earlier by Lorenzo Pieralisi. Basically
a single interface cpu_enter_idle takes care of saving and restoring single 
cpu or whole cluster information.  The link to the framework patchset is,
http://www.spinics.net/lists/arm-kernel/msg132044.html

Description of patches in this list:
1)Patch (ARM: kernel: Some fixes in save/restore common code) adds some
essential fixes for the common save/restore to work on exynos4 platform.

2)Patch (ARM: EXYNOS4: Fix to work with origen boards) adds a fix for 
extracting chip revision number.

3)Patch (ARM: EXYNOS4: Add support AFTR mode cpuidle state on EXYNOS4210) 
rebases the L2 retention C state cpuidle driver submitted earlier by 
Jaecheol Lee.

4)Patch (Modify cpuidle code to adapt to save/restore common code) uses the
generic infrastructure to enter and exit from the retention idle state. 

All these codes have been tested on Samsung ORIGEN board against the tree
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git for-next.
