Log:
Increment td->td_intr_nesting_level for LAPIC timer interrupts. Among other
things it hints SCHED_ULE to run clock swi handlers on their native CPUs,
avoiding many unneeded IPI_PREEMPT calls.
Will this help SCHED_4BSD at all? I'm finding it to be slightly better
for interactivity on a loaded system, but frankly at this point they
both leave a lot to be desired.
