Subject: Re: [PATCH 0/3] explicitly document overloaded page flags V2

Looks good.

If we want to do the bit aliasing at the PG_xxx layer then there may be a 
way to simplify the page flag generation function because the xxx in 
PG_xxx is always the lower case of the PageXxx case. So we could remove 
one parameter if we can find some kind of cpp function that can lowercase 
a text.
