Whats the reasoning for changing order here? Is this sorted somehow?
Would it make more sense to use an enum to define the bits instead so
that patches don't have to do a -/+ of the same NAME?

IMO not really worth re-rolling the series over, it just made it a bit
more work to read the patch as I was reviewing.
