That's the right data structure to look at for arch code. Accessor functions are provided. irqd_is_per_cpu(irqdata); irqd_can_balance(irqdata); Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Its' too ugly and needs to go. The only users are core code and parisc. Core code does not need it and parisc gets a new check once IRQ_PER_CPU is reflected in irq_data.state. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The saving of this switch is minimal versus the ifdef mess it creates. Simple enable PER_CPU unconditionally and remove the config switch. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

chip implementations need to know about it. Keep status in sync until all users are fixed. Accessor function: irqd_is_setaffinity_pending(irqdata) Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Some chip implementations need to access certain status flags. With sparse irqs that requires a lookup of the irq descriptor. Add a state field which contains such flags. Name it in a way which will make coders happy to access it with the proper accessor functions. And it's easy to grep for. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

We need to maintain the flag for now in both fields status and istate. Add a CONFIG_GENERIC_HARDIRQS_NO_COMPAT switch to allow testing w/o the status one. Wrap the access to status IRQ_INPROGRESS in a inline which can be turned of with CONFIG_GENERIC_HARDIRQS_NO_COMPAT along with the define. There is no reason that anything outside of core looks at this. That needs some modifications, but we'll get there. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The irq_desc.status field will either go away or renamed to settings. Anyway we need to maintain compatibility to avoid breaking the world and some more. While moving bits into the core, I need to avoid that I use any of the still existing IRQ_ bits in the core code by typos. So that file will hold the inline wrappers and some nasty CPP tricks to break the build when typoed. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

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>

All archs implement show_interrupts() in more or less the same way. That's tons of duplicated code with different bugs with no value. Implement a generic version and deprecate show_interrupts() Unfortunately we need some ifdeffery for !GENERIC_HARDIRQ archs. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

IRQ_MASKED is set in mask_ack_irq() anyway. Remove it from handle_edge_irq() to allow simpler ab^HHreuse of that function. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <20110202212551.918484270@linutronix.de>

Now that everything uses the wrappers, we can remove the default functions. None of those functions is performance critical. That makes the IRQ_MASKED flag tracking fully consistent. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

Aside of duplicated code some of the startup/shutdown sites do not handle the MASKED/DISABLED flags and the depth field at all. Move that to a helper function and take care of it there.

The if (chip->irq_shutdown) check will always evaluate to true, as we fill in chip->irq_shutdown with default_shutdown in irq_chip_set_defaults() if the chip does not provide its own function.
