This patch series fixes the cpuidle for different states. Also removes arm diagnostic and power register save/restore code as it is made generic.

Based on:
ARM: save/restore diagnostic register on Cortex-A9 suspend/resume

As there is an outstanding issue with this patch, we can't proceed with this set of changes until we know what's going on there.

Sure, I will wait for the conclusion.

So I believe the conclusion was that this can't be handled in generic way, because on systems running in non-secure mode writing to those registers faults.

However I believe this could be moved into generic helpers.

Best regards,
Tomasz
