I think that is indeed a SPARCv7 chip. Looks like the "sun4m implies
sparcv8" rule is not entirely hard and fast.
Globally enabling kernel emulation of umul for sun4m shouldn't do any
harm, so that seems like the best approach. Or, if one wanted to be
really careful, the kernel does know the exact cpu model so the
emulation could be enabled only for those Cypress parts.
