--- Comment #17 from Shawn Anastasio (shawn@anastas.io) ---
On second glance, it seems I got it backwards. pgprot_noncache /is/ actually
being set via the default implementation of arch_dma_mmap_pgprot, but this
creates the opposite issue. In the coherent case, the vma is now marked
as noncache but in the previous implementation it was not. I'll post a new
patch to solve this by providing a powerpc implementation of
arch_dma_mmap_pgprot that only sets noncache in the !coherent case to match
the previous behvaior.
