NAK -- I hit this problem too, but in fact the errata configs should not
really be dependent on SMP; these are fixed in a couple of patches
currently queued in Russell's patch system:

7196/1 - errata: remove SMP dependency for erratum 720789
7197/1 - errata: remove SMP dependency for erratum 751472

...so we should avoid duplicating knowledge about exactly what these
errata workarounds do, where it can be avoided.

In the meantime, the warning is harmless.

Cheers
---Dave
