Log message:
kernel: expand fixed clock interrupt periods to 64-bit values
Technically, all the current fixed clock interrupt periods fit within
an unsigned 32-bit value. But 32-bit multiplication is an accident
waiting to happen. So, expand the fixed periods for hardclock,
statclock, profclock, and roundrobin to 64-bit values.
One exception: statclock_mask remains 32-bit because random(9) yields
32-bit values. Update the initclocks() comment to make it clear that
this is not an accident.
