I think all these changes need to be reviewed in their entirety even though some patches do look good on their own. For example this patch depends on whether [PATCH 03/35] is acceptable or not. I would suggest separating out CMA patches which could be debated and merged regardless of this series. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
