You need to go search the archives and read the *extensive* thread

Various good points were raised. The NX bit requiring
3-level pagetables suggests that 3-level pagetables without highmem
would be valuable, at which point the unaligned splits to avoid highmem
with 3-level pagetables gain additional relevance. I'll queue that up
to be written along with split pmd affairs, and check for features
dependent on 4-level pagetables, too.
Excellent! That would be super to have in there, William.
Cheers!
