[PATCH v2 0/5] follow-up "Optimize CONFIG_DEBUG_PAGEALLOC"

[js1304]

From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>

v2) Changes
o fix powerpc build failure (basic build test done)
o export symbol for module build
o change comment and clean up code

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.

Andrew, there is mis-spelled word (compliled -> compiled) in commit
description so I re-send all. Except powerpc one, others are basically
same with the patches on your tree.

Thanks.
