+u64 sched_clock_cpu(int cpu)
+{
+ if (unlikely(!sched_clock_running))
+ return 0;
+
+ return sched_clock();
+}

This looks like it will solve the issue on the boot cpu. It
leaves a potential hole as we bring up other cpus if[1] there
are any printk() calls before they get to cpu_init() to
initialize ar.kr3. This code path is all under arch/ia64
though ... so if we shoot ourselves in the foot, it will be
our own fault.

[1] Currently there is just one Dprintk() call in this path
at the start of start_secondary() ... I could put it inside
#ifndef CONFIG_PRINTK_TIME so as not to surprise anyone that
enabled it.
