John Baldwin abd9053ee4 Blow away the panic mutex in favor of using a single atomic_cmpset() on a ... panic_cpu shared variable. I used a simple atomic operation here instead of a spin lock as it seemed to be excessive overhead. Also, this can avoid recursive panics if, for example, witness is broken.		2001-04-17 04:18:08 +00:00
