genirq: Protect tglx from tripping over his own feet 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>

genirq: Add IRQ_INPROGRESS to core 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>
