The Linaro Kernel Working Group (KWG) and the Linaro Platform Group are excited to announce the availability our February 2012 development snapshot:
linux-linaro-3.3-rc3-2012.02-1
As the word "snapshot" implies, these are meant as development kernels and have not been fully validated. You should expect issues and to help us deliver a better kernel in the future, please file bugs in Launchpad at https://bugs.launchpad.net/linux-linaro.
We are excited about our first -rc based kernel as we move to a new process that will provide early access to more bleeding edge features on member-supported LEBs.
The source tarball is available at: http://launchpad.net/linux-linaro/3.3/3.3-rc3-2012.02/+download/linux-linaro...
The kernel sources can also be accessed using git at: git://git.linaro.org/people/ynk/linux-linaro-tracking.git tag: linux-linaro-3.3-rc3-2012.02-1
This kernel includes the following changes from the 2011.11 kernel:
- Update to 3.3-rc3
- Various patches from Linaro
* samsung_cpuidle_l2_retention patch set from the power management WG * thermal_cpu_cooling patch set from the power management WG * irq_domain patch set from Grant L. (cherry-picked from linux-next) * Fix for https://bugs.launchpad.net/bugs/918412 * Basic device tree board support for supported ARM boards (comes from linux-linaro-3.1) * sched: Ensure cpu_power periodic update (Vincent G.) * ARM: kprobes: work around build errors (Arnd B.) * usb: ehci: make HC see up-to-date qh/qtd descriptors ASAP (Ming L.) * Perf: Fallback to /bin/more if less is not found for perf pager (Avik S.)
A full change log against the 3.3-rc3 release is available at: http://launchpad.net/linux-linaro/3.3/3.3-rc3-2012.02/+download/CHANGELOG-li...

Amit, is this now in your maintainer's tree queued up for 3.4?
Hi Amit Kucheria,
I have asked the samsung maintainer(Kukjin Kim) to queue this patch set 1 month back. But seems like it is not present.
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.ht...
Thanks, Amit Daniel

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 kukjin Kim,
I was on travel for elc and linaro conferences so little late for replying. Thanks for testing these patches. I just submitted the V6 series of the cpuidle patchset. I rebased it against the 3.3-rc4 kernel version. I also tested it for SMDKV310 (evt1) and Origen (evt1.1) boards and they are working fine. Some modification was done for CHECK_FLAG.
Thanks, Amit Daniel

OK, I checked it works fine on SMDKV310 now. As I said, will apply your patches for v3.4 but I'm not sure there is a problem with common cpuidle work.
Anyway, good job.

These patches could be part of your for-next branch (and available for v3.4 merge) and any work on common cpuidle code would be incremental changes to this patchset.
