Thanks.

(The target clause is redundant fwiw, feel free to remove it).

This selector doesn't make too much sense, since nothing in here
requires vectors at all. p9modulo_hw makes more sense. Except the
name of that should just be power9_hw :-)
The OS can disallow vector insns (MSR[VEC] and/or MSR[VSX]), so
p9vector_hw tests it isn't doing that, and that the hardware is a p9.
p9modulo_hw does only the latter, and we have no reason to check
separately if we can run modulo insns anyway :-)
So please change the test here. And bonus points if you can rename
p9modulo_hw and _ok (in a separate patch of course).
