Hi Amit Kucheria,
Hi all,
(Cc'ed Jaecheol Lee and Jongpill Lee)
I have asked the samsung maintainer(Kukjin Kim) to queue this patch set 1 month back. But seems like it is not present.
If it works fine, then I'm apply this series.
But now it is not working. As a note, I use your series on top of v3.3-rc3 and fixed following for test.
arch/arm/mach-exynos/cpuidle.c: In function 'exynos4_enter_core0_aftr': arch/arm/mach-exynos/cpuidle.c:119: error: implicit declaration of function 'BSYM' make[1]: *** [arch/arm/mach-exynos/cpuidle.o] Error 1
I and Jaecheol Lee tested AFTR mode on SMDKV310 and SMDKC210 and then rebooting happened. See below log.
If any updates, please let me know.

Hi Mr Kim,
Can you please queue this patchset in your tree for next merge window? The V5 version submitted fixes all the known issues. http://lists.infradead.org/pipermail/linux-arm-kernel/2012- January/079214.html
Thanks, Amit Daniel

Amit, is this now in your maintainer's tree queued up for 3.4?
