As CONFIG_DEBUG_PAGEALLOC can be enabled/disabled via kernel parameters we can optimize some cases by checking the enablement state. This is follow-up work for Christian's Optimize CONFIG_DEBUG_PAGEALLOC. https://lkml.org/lkml/2016/1/27/194 I can't test patches for sound, power and tile, so please review them, maintainers. :) Remaining work is to make sparc to be aware of this but it looks not easy for me so I skip that in this series. It would be the best that these paches are routed through Andrew's tree, because there is a dependency to MM. Thanks.
