          [PATCH v2 0/4] ahci: misc fixes/tests for 2.4

This series adds a couple of tests to exercise the NCQ pathways
and establish a baseline for us.

Most of these patches are fairly short and should be relatively trivial
to review. this series will lay the groundwork for part 2,
which adds the rerror/werror=stop and migration support for that feature
as well.

===
v2:

 - Cleared out #ifdefs to prevent unneeded bitrot
 - Fixed migration test in patch 16
 - Removed the forceful ide_state->error clear from patch 08,
   replacing it instead with a change to the tests to issue
   IDENTIFY prior to attempting any data transfer.
