Hey, I remembered that there's an option to put third level page tables 
in highmem.

This might be a stupid question, but is there a way to move more kernel 
data into highmem?

For example, page directories, first level page tables?

I even remember a few articles on lwn about how much space is taken up 
by struct page.
