Usual convention is to have status the last. Maybe MIPS has different,
so keep whatever is consistent in your case.

Anyway:

I'll send out a fixup patch that can be folded into this. Hopefully 
Thomas can combine them at his end (or if there is a need for a v6 I can).

I'll probably have other series touching this file so if the fixup 
doesn't make it now I can include it in a future series.
