I'm really just trying to avoid the bugs we have where people look at page->mapping and the compiler can't say "this is a tail page, that doesn't do what you think it does". Everybody keeps trying to get me to solve their problems as well.

Please, just let me solve a problem, not rewrite the entire kernel.

I don't want you to rewrite the whole kernel! I'm just contemplating how it _could_ be rewritten if someone were inclined to do so.

(Also, I do care about the KVM mess, and I don't think KVM could have dug itself into quite the hole its in if there hadn't been a struct page to begin with for most user mappings, but fixing that needs a rewrite and a time machine.)
