ARM/ARM64 architected timer updates for v3.12, take 2

Hi Daniel,

These are the ARM/ARM64 arch timer updates for v3.12.
I have re-based the changes on tip/timers/core as there are conflicts with memory mapped arch_timers support queued recently. Since this series adds CPU PM notifiers for arch_timers, it is required to enable ARM bL cpuidle drivers(already queued for v3.12)

Russell said he wants someone from ARM to ack it, Will did the same. For ARM64, Catalin acked. I have updated the branch accordingly. If not too late, please do consider it for v3.12

Regards,
Sudeep

Hi Sudeep,

I don't see the acked-by from Olof or Kevin.

Your patchset touches files under arch/arm which are maintained by them and I won't take the patchset if they don't agree the modifications on the files falling under my umbrella that will pass through my tree.

Please do it ASAP if you want a chance to hit 3.12, it is already very late.

Thanks
-- Daniel

As Olof already mentioned, I think its too late for v3.12. He wants me to repost after v3.12 merge window. I will do the same.

Sudeep
