Description

The sparc64/shared/clock driver has a bug that causes nested timer interrupts to not be serviced, which leads to non-preemptive behavior especially when dispatching work from the timer ISR.

The attached patch fixes the nesting issue by correcting the PIL after reading the tick and setting the tick_cmpr registers. The patch also corrects a typo.
