genirq: Add internal state field to irq_desc
That field will contain internal state information which is not going to be exposed to anything outside the core code - except via accessor functions. I'm tired of everyone fiddling in irq_desc.status. core_internal_state__do_not_mess_with_it is clear enough, annoying to type and easy to grep for. Offenders will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
