o Register ISR INTR_MPSAFE. o Loop on KTHREAD_DONE == 0 in the thread. o Safe the INTR_MPSAFE flag for client drivers (don't know if there are any CardBus/PCI drivers that are INTR_MPSAFE) o Read status after acquiring mtx_lock(Giant) rather than before so that we catch state changes that happen while Giant is being acquired. o Turn off the CD bit when we see a CD interrupt, and turn it back on after we've attached/detached the card. o On suspend, actually set the CBB_SOCKET_MASK to zero rather than oring in '0' to turn it off on suspend. o If the ISR that's registerd is MPSAFE, don't acquire Giant around call to client ISR. o Fix comments to reflect these changes.
