sys/sparc64/sparc64 exception.S interrupt.S
Log:
MFC: sys/sparc64/sparc64/exception.S 1.73,
sys/sparc64/sparc64/interrupt.S 1.9
- In intr_fast() fix a race which is fallout from critical sections no longer
raising the PIL and can cause corruption of the interrupt request lists.
- In intr_fast() assert that the ir_func to be called is non-zero.
- Increment interrupt stats after calling the handlers rather than before in
order to reduce the delay until direct and fast handlers are serviced.
