/* hardirq.h: PA-RISC hard IRQ support.
*
* Copyright (C) 2001 Matthew Wilcox <matthew@wil.cx>
- *
- * The locking is really quite interesting. There's a cpu-local
- * count of how many interrupts are being handled, and a global
- * lock. An interrupt can only be serviced if the global lock
- * is free. You can't be sure no more interrupts are being
- * serviced until you've acquired the lock and then checked
- * all the per-cpu interrupt counts are all zero. It's a specialised
- * br_lock, and that's exactly how Sparc does it. We don't because
- * it's more locking for us. This way is lock-free in the interrupt path.
