Hmm. Why? Why can't the work of the constructor not be done after the
kmem_cache_alloc() ?

I can do that for pte/pmd. Never quite understood why those were made
slabs -- on x86-64 they are just pages and that works great.
But in PAE pgd is only 32 bytes. That will always need a smaller allocation.
But that shouldn't be overloaded anyways.
Actually I think it could be probably just put into mm_context_t
