Done. Available here:

These drivers need work to replace vb2_plane_vaddr by
vb2_plane_begin/end_cpu_access():

$ git grep vb2_plane_vaddr

drivers/media/platform/coda/coda-bit.c:                 if (((char *)vb2_plane_vaddr(buf, 0))[i] != 0)

The coda and exynos4-is I never converted and the others are new.
