5 | * The locking is really quite interesting. There's a cpu-local | ||
6 | * count of how many interrupts are being handled, and a global | ||
7 | * lock. An interrupt can only be serviced if the global lock | ||
8 | * is free. You can't be sure no more interrupts are being | ||
9 | * serviced until you've acquired the lock and then checked | ||
10 | * all the per-cpu interrupt counts are all zero. It's a specialised | ||
11 | * br_lock, and that's exactly how Sparc does it. We don't because | ||
12 | * it's more locking for us. This way is lock-free in the interrupt path. | ||
