OK, in 2.6.35, linux-source, on line 328 in /kernel/time/tick-sched.c, this is
what I see:
if (rcu_needs_cpu(cpu) || printk_needs_cpu(cpu) ||
<328> arch_needs_cpu(cpu)) {
next_jiffies = last_jiffies + 1;
delta_jiffies = 1;
whereas in 2.6.36 linux-source, I see this:
if (rcu_needs_cpu(cpu) || printk_needs_cpu(cpu) ||
<328> arch_needs_cpu(cpu)) {
next_jiffies = last_jiffies + 1;
delta_jiffies = 1;
OK. so this does not help. -:(
Still sharing the results of my findings.
