 /* hardirq.h: PA-RISC hard IRQ support.
  *
  * Copyright (C) 2001 Matthew Wilcox <matthew@....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.
