+1 on all the points above ;)(I may also be getting things wrong here
but I am not convinced that we can resolve the issue for all the ARM
vendor possible combinations we may have to address)

We should come up with some *magical* cpumask that we can use if we
want to retain this write capability. And only way I see we can do that
is using DT which in turn eliminates the need to have write capability
for this sysfs.

So I am going to ack the $subject patch for now.
