That's was today's "little" task. I was just in the process of writing an email :-)
It got me to the following commit:
commit 64b3d0e8122b422e879b23d42f9e0e8efbbf9744
Author: Benjamin Herrenschmidt <benh@kernel•crashing.org>
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.
