In similiar manner of the original SATA driver model, the one that
didn't use the SCSI stack. Then the SATA model was enhanced to fit
under SCSI, then the SATA drivers ported to run under the SATA module.
At that point, the original SATA driver model was an exception to the
SATA model.

Yes, if all the world used the hardware MCE mechanism, then the MCE
device probably would satisify the requirements. But since linux runs
across so many architectures and processors, the export of a single
architecture's mechanism then implies that a second interface is
necessary anyway in order to provide for those "other" archs. 

At that point we then move the abstraction into userspace anyway.
Scripts will then need to "know" which arch they are on, in order to
pull ECC events from one or the other interface.

Thus, where is the line as to where the "portable" abstraction "fits"?

thanks for your comments
