Hmm, I think you are right:

I would say it is:

static irqreturn_t jcore_timer_interrupt(int irq, void *dev_id)
{
        struct jcore_pit *pit = dev_id;

	OR

	struct jcore_pit *pit = this_cpu_ptr(jcore_pit_percpu);

	[ ... ]
}

The former the better for the encapsulation.

Do you mind to update the patch ?
