Hi Thomas, Would you be happy for this patch to be taken via the arm64 tree? The next patch [1] makes use of this in the arm_pmu driver, and we're likely to have some other changes there shortly.

Hi Thomas, I was hoping to merge this one via arm64 since it now has Marc's Reviewed-by, but I'd really like your Ack on it too, if you don't mind. Could you take a look, please?

irq_is_percpu indicates whether an irq should only target a single cpu. PERCPU_DEVID flag indicates that an irq can be configured differently on each cpu it can target. Provide a function to check whether an irq is PERCPU_DEVID.
