Hannes, whilst I don't want to explicitly make things harder for the -rt
folks, I don't think it's appropriate to put unnecessary preemtption
disables into the main kernel like this.

Someone reading the code as-is will say this is superfluous and (correctly)
submit a patch to remove the preemption disables.

Please remove this from your patch, someone can deal with this in the
-rt kernel as needed.
