I think the culprit is:
commit c30700db9eaabb35e0b123301df35a6846e6b6b4

dma-direct: provide generic support for uncached kernel segments
Ad it turns out I can't just apply this fix to the dma-mapping tree
because it doesn't have the m68k changes. So either you'll have to
queue it up, or I'll have to do secondary pull request to fix up
the first one. Maybe it is eiter if you just send it to Linus
before I send the dma-mapping PR?
