I don't think we should have a CONFIG_DEBUG_PAGEALLOC that does some stuff 
and then a commandline parameter or CONFIG_DEBUG_PAGEALLOC_ENABLE_DEFAULT 
to enable more stuff.  It should either be all enabled by the commandline 
(or config option) or split into a separate entity.  
CONFIG_DEBUG_PAGEALLOC_LIGHT and CONFIG_DEBUG_PAGEALLOC would be fine, but 
the current state is very confusing about what is being done and what 
isn't.

Ping?

That's already in linux-next so I can't apply it.

Well, I can, but it's a hassle.  What's happening here?
