Thanks Nick, The referenced commit was pulled from Andrew's tree and subsequent versions of next.

Hopefully, there is a some way to do this without potentially touching a bunch of arch code. -- Mike Kravetz _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
