Interaction with irqbalancing?
Can you elaborate ? Do you mean we check irq affinity for a offlined cpu is moved to another cpu ? Or something like that ?
yeh if you've tied some important interrupts to a CPU that disappears what happens to the interrupts.

Right. I am not sure what interactions we really want to check in the test suite but we have to keep this in mind.
Well I'm not too sure which types of scenarios you're looking to hotplug CPUs on ARM, but generally I'd say try and do the normal types of suspend/resume cycles or power save changes having hotplugged before hand (or if you want to be particularly evil during the process).
