timers: /proc/sys sysctl hook to enable timer migration
* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-04-16 12:11:36]:
This patch creates the /proc/sys sysctl interface at
/proc/sys/kernel/timer_migration
Timer migration is enabled by default.
To disable timer migration, when CONFIG_SCHED_DEBUG = y,
echo 0 > /proc/sys/kernel/timer_migration
