Subject: [PATCH 0/2] mm: Always use set_pXX() helpers to write page tables

As Ryan Roberts points out[1], when writing page tables, generic mm code
should already be using the architecture-provided helper functions.
This series includes fixes for the few instances where we didn't do
that, as found by my coccinelle script[2].
