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.
