Log message:
Use an IPI, so hw.setperf affects all cores in the mp kernel.
Before, apm -A was speeding up only one core of my POWER9.
Now, apm -A speeds up all cores, so my parallel builds are faster.
I copy the idea from amd64 and i386: mp_setperf() sends an IPI to all
cpus; the interrupt handler calls ul_setperf().
