Did you get these patches in too:
25021c9 x86: define arch_vm_get_page_prot to set _PAGE_IOMAP on VM_IO vmas
2eb6682 drm: recompute vma->vm_page_prot after changing vm_flags
dbbc947 ttm: Set VM_IO only on pages with TTM_MEMTYPE_FLAG_FIXED set.

Yes, and those three I mentioned earlier should suffice as a temporary solution.
