/sparc*/xtensa are replaced with smp machine properties. No semantic changes.

if I didn't recall what rules might be, I wouldn't understand what it is about.

It would be better to rephrase commit message and make it more verbose,
note that commit message exists not only for reviewers but also
for whomever comes later (without knowing about implied context).
So commit message should explain insufficient details what patch is doing.
