2f95f7cda8 Modify interrupt load balancing policy on reboot/stop
When rebooting:
1. Stop irqbalance
2. Modify /proc/irq/*/smp_affinity so that McKernel cores are not
   included
3. Start irqbalance with McKernel cores and IHK IRQ banned from
   load balancing

When stopping:
1. Stop irqbalance
2. Restore /proc/irq/*/smp_affinity
3. Restart irqbalance with the system default settings

1ce1b17a85 Specify facility used by mcklogd via option
1. You can specify facility through -f option of mcreboot.sh.
   Example:
   mcreboot.sh -k 1 -f LOG_LOCAL6
   Note that you need to specify "-k 1" or "-k 2" to start mcklogd.
2. Kill mcklogd if needed in mcreboot.sh and mcstop+release.sh.
