It's basically the same way that the init code uses it. When
initialized, a struct page has it set. In theory, an architecture could
decide to keep the bit set when it is doing online_pages(). However, I
don't think any do that today. Nobody would really notice if we killed
that. That check could probably instead be something like
page_is_ram().
