/* hardirq.h: PA-RISC hard IRQ support.

|
||||
*
|
||||
* 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.
