Hi Russell, all,
even though I think this set is ready to get merged, it would be great if we can test it on as many platforms as possible since it touches core suspend/resume operations on ARM platforms relying on
CONFIG_ARM_CPU_SUSPEND, and there are many.FWIW, I booted a Tegra system with these patches applied and didn't see any issue in very brief testing. I'm not sure what targeted testing would be useful?
That's great thanks. CPUidle deep C-states (when CPUs resume from reset through
cpu_resume) are the main triggers of this code, so you should be running with them enabled to test it.

OK, in that case I believe I tested that; I had our "LP2" CPU power-management mode enabled as always, and that powers off the CPUs and resumes them, and didn't see any issue.
Great, thanks, I guess this also means you did not notice any suspicious warnings at boot (ie "Large number of MPIDR hash buckets detected").
I didn't, although I didn't look that hard for them!

Can I add your tested-by please ?
Sure.
