sys/i386/include smptests.h
Log:
Add interrupt counters for IPIs. By default they are disabled, but they
can be enabled by enabling COUNT_IPIS in smptests.h. When enabled, each
CPU provides an interrupt counter for nearly all of the IPIs it receives
(IPI_STOP currently doesn't have a counter) that can be examined using
vmstat -i, etc.
