Ugg, these affect the ahci code heavily, the changes look nicely done
and if they get upstream then they would be ok I guess but they are
large and complex.

We are going to need some good testing on existing ahci bits on the
results here.  Risk == high.

The rest of this looks pretty self contained and low risk.
