Modified Files:
src/sys/arch/alpha/include: cpu.h
Log Message:
Fix fallout from alpha/interrupt.c rev 1.93:
http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/alpha/alpha/interrupt.c#rev1.93
by which interrupts *seem* to occupy 100% CPU time.
Now, we bump ci_intrdepth for clock interrupt. Therefore, if ci_intrdepth > 1
is observed in statclock(), CPU is actually occupied by interrupts.
Thanks jklos and thorpej for notice!
