Yeah, I know.  I guess you know my but-what's-the-actual-punishment
argument too by now.

This is about time we make decision on this.  If we're gonna go
DMA-for-everything way, we should lift 16 byte default masking for -mm
and -rc's as that only makes debugging difficult and try to blacklist
offending devices and controllers individually.

My primary concern is about not achieving enough test coverage and
isolated cases where it's difficult to tell whether it's the device or
the controller.  e.g. Loading recent distro on an ancient and/or strange
machine, scratching head while cursing and giving up.  Unfortunately,
I've seen similar things happening often enough (and I did so myself
more times than I'm proud of).  Only very small fraction of problems
actually reaches developers.

Thanks.
