Log message:
Switch to an MI implementation of kmap_atomic() and implement
kmap_atomic_prot(). Use this to unstub ttm_copy_io_ttm_page()
and ttm_copy_ttm_io_page(). This fixes suspend/resume of machines
with certain radeondrm(4) hardware.
Based on a diff from jsg@. Tested by Edd Barrett and Alf Schlichting.
