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>
