Thanks Viresh. :-)
I'm tidying up my TC2 power management branches, then I'll test it all with the new bit-LITTLE-MP-v4. If all goes well then I can get Andrey to add the TC2 PM branch to linux-linaro and we'll have everything integrated in one place. :-)

Great! I am pulling big-LITTLE-MP-v4 into linux-linaro-core-tracking (v3.5 based). linux-linaro is currently frozen due to the 12.07 release. After 12.07 is out, I can add big-LITTLE-MP-v4 and the TC2 PM to linux-linaro. Also I am on vacations next week, so there may be additional delays for the merge requests done next week.
Thanks, Andrey

Andrey, can you add a new topic to linux-linaro from the ARM LT git? [1] The branch is tracking-armlt-tc2-pm and it is stacked on top of the existing topic tracking-armlt-tc2.
Note, this includes 4 cpuidle patches from Colin Cross which are also in the bit-LITTLE-MP, will this be a problem?
Hi Viresh,
big-LITTLE-MP-v4 has been merged into linux-linaro-core-tracking, tag llct-20120725.0
Thanks, Andrey

Hello, Viresh,
You are missing some fixes, please see below. I can also email you the updated patches, if that would be easier than pulling them from -rcu.

Hi Andrey,
So sorry, but you need to pull v4 again as there were few updated patches from paul. :( Can you please pull this again?
I have created another branch for new fixes from Paul, per-cpu-thread-hotplug-v3-fixed, as it wasn't a v4 actually.
I have updated the same merge branch big-LITTLE-MP-v4 that you can pull in.
@Paul: I have applied all three changes you suggested, please see if everything is fine now.

Sure, no problem. The updated big-LITTLE-MP-v4 topic has been merged into linux-linaro-core-tracking tree, the tag is llct-20120726.0
