Bruce Evans a84c84f5b0 Reduce i/o overheads by not preserving the channel access register in
interrupt handlers.  Instead, load and use it atomically as necessary.
This reduces mode switching overhead for "polled" mode interrupt handling
from 5 i/o's to 3 (per service type, per port) so that polled mode is only
slightly more inefficient than "interrupt" mode.
