	src/sys/arch/sparc/sparc: cpu.c cpuvar.h intr.c

Log Message:
Optimize xcall() et.al. further by maintaining a cpuset mask of all CPUs
marked ready. This saves repeated testing for NULL pointers and the
CPUFLG_READY flag.
Also use a separate flag variable to signal xcall completion. This saves a
load and a pipeline stall.
