microblazeel works with this patch,
Awesome... Andrew in my rush yesterday I should have put a reported by on the patch for Guenter as well.
Sorry about that Guenter,
No worries.

as do the nosmp sparc32 boot tests, but sparc32 boot tests with SMP enabled still fail with lots of messages such as:

I'm really not seeing how this is related to the kmap clean up.
But just to make sure I'm trying to run your environment for sparc and having less luck than with microblaze.
Could you give me the command which is failing above?

Code path leading to that message is different but always the same from free_unref_page().
Still testing ppc images.
ppc image tests are passing with this patch.
