The patch was 4/4 of course. :-<
Probably I was too esctatic about the code. ;-)

The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the MWDMA modes (at least that caould be seen in their so-called drivers :-),
so the driver needs to account for this -- to achieve this:

- add mdma_filter() method from the original patch by Bartlomiej Zolnierkewicz
with his consent, also adding the method callout to ide_rate_filter();

- installed the method for all chips to only return empty mask if a SATA drive
is detected onHPT372{AN]/374 chips...

This patch against the current Linus' tree and unfortunately I was able to only
compile test it since that tree gives MODPOST warning and dies early on bootup.
Will hopefully try to test if/when I have time... :-)
