Wake up All interrupts on cpu0

For any experimentation reasons, we  might have to to wake up all interrupts on cpu0.

For Example:

Lets say if you want to wake qemu IO thread to get waken up on cpu0 all the time.

1) Disable irqbalance

service irqbalance stop

chkconfig –level 123456 irqbalance off

And then reboot.

2)  Check smp_affinity of any process.

[root@psuriset home]# cat /proc/irq/10/smp_affinity
00ffffff
[root@psuriset home]# cat /proc/irq/110/smp_affinity
00ffffff
