The disadvantage of this would be to cut off users that have Power 7
systems
and optimized code.  So why would people want to optimize from Fedora 21 to
Fedora 22.  You would be taking a big step back in performance.  I don't
want to suggest keeping a subarch for each type of POWER system out there.
I
was thinking of keeping two.  So when the next POWER arch that comes out,
the Power 7 subarch goes away and you would have Power 8 and the new Power
arch.
