Re: [PATCH 08/15] mips: switch to generic version of pte allocation

isn't quite true - we don't use __GFP_ZERO in pte_alloc_one() & instead call clear_highpage() on the allocated page. Not that I have a problem with using __GFP_ZERO - it seems like the more optimal choice. It just might be worth mentioning the change & expected equivalent behavior.
