Not everywhere. Drivers will work fine without any changes, but will
work faster if readX is turned into readX_relaxed in the fast paths
where DMA completion isn't important. In the lkml thread that discussed
this feature everyone seemed to agree on that approach. Would you
rather have a different interface?
Thanks,
