Dear Michael,

Constants seem to be correct values still, nice. That said, the other
patches that have come through from others before this prevent this
applying to my copy of staging-testing branch. Assuming Greg takes the
patches in order, this will therefore need reworking. That said, it
builds fine for me when applied directly to fresh staging-testing tip
without the patches that have come in since, so:

Acked-by: Phillip Potter <phil@xxxxxxxxxxxxxxxx>

By all means apply that Acked-by to v2 if needed. Many thanks.

Regards,
Phil
