Subject: [PATCH 0/5] follow-up "Optimize CONFIG_DEBUG_PAGEALLOC"

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.
