  powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDED

I tried reverting it, but as I had kinda thought, that really didn't help.

I'm just recompiling to check that I didn't screw-up during the bisection.

Is this a chip that must not have M set ? Or something else ? You guys
have to help if you CC me, I have about 0 idea what a MPC8661d is :-)


Sorry, my fault. It's a Freescale SOC with two e600 cores. Beyond that, I'm afraid I'm a little out of my depth.
Also, does 4c456a67f501b8b15542c7c21c28812bf88f484b help ?

I believe that to be included in 2.6.29-rc3 if my (rather rudimentary) git 
skills haven't let me down? The problem persists in 2.6.29-rc3.
