disarm_decr[] is defined as an unsigned long array but never get
initialized in arch/ppc/kernel/time.c.
What's the purpose of using disarm_decr? I read the timer_interrupt()
code and found the only place where it's referenced.
int timer_interrupt(struct pt_regs * regs)
{
...
if ( !disarm_decr[smp_processor_id()] )
set_dec(next_dec);
last_jiffy_stamp(cpu) = jiffy_stamp;
...
}
So in this case, the value of disarm_decr[] is always zero, right? Then
the decrementer get set each time when the timer interrupt is invoked.
