IDE already supports rerror and werror. I guess this series fixes
migration bugs that can bite when rerror/werror=stop. Correct?
IDE over PCI supports rerror and werror. IDE over ISA does not.
This series makes it possible to support it very easily, see patch 13.

Yes, sorry -- rerror=stop/werror=stop already worked for PCI/BMDMA, but
this series as a whole unifies the resume pathways and irons out some
migration issues.
Most notably, as Paolo states, this fixes ISA and my later patches fix
AHCI. AHCI tests are still dependent upon enabling migration, so those
aren't here yet, but I sat on this series until I convinced myself that
AHCI was working too, hence the delay.
The practical upshot is that rerror/werror work for all the acronyms
listed using newly unified code pathways.
