Is "supports" the best word here?

A CPU is based on a microarchitecture, it doesn't really support it.  I
guess we could say the CPU supports a microarchitecture's *features*,
but that's a bit wordy for a tiny comment.

Maybe:

#define X86_FEATURE_ZEN			(7*32+28) /* "" CPU based on Zen uarch */

or spell out "microarchitecture" if there's room.
