Modified files:
sys/ia64/ia64 interrupt.c
Log:
* Add some KTR messages for IPIs.
* Don't call ast() from interrupt() - if we switch, then we will miss
writing cr.eoi which will prevent the current cpu from receiving
interrupts until the current thread is resumed. The call to ast()
happens magically in exception_restore where it is safe.
* Add DDB 'show irq' command to examine interrupt hardware state.
