While I'm generally in favor of using macros where they exist, I do agree with
Henrique that this is actually less legible.

Indeed. 1285 patches with the same subject line is "not ideal". Prefixing with
the subsystem at the very least would have been an improvement. An RFC on the
concept, cc'ing the subsystem maintainers to get consensus and direction on how
to manage the large change would have been advisable.

I'm dropping these for pdx86 unless a compelling argument arises for including
them (like - the only subsystem not taking these is pdx86...)
