From: Andi Kleen <ak@xxxxxxxxxxxxxxx>
When the "default y" CONFIG_NUMA_BALANCING_DEFAULT_ENABLED is enabled,
the message it prints refers to a sysctl to disable it again.
But that sysctl doesn't exist.
Document the correct (highly obscure method) through debugfs.
This should be also in Documentation/* but isn't.
Also fix the checkpatch problems.
BTW I think the "default y" is highly dubious for such a
experimential feature.
