Before I approve that I'd like to hopefully see some numbers across
the M-class cores as well so that we make sure that side of the
architecture isn't missed out (I don't expect it to make a huge
difference there but it's still worth checking) - I'm quite happy for
it to be default on A8 and A9 based on the evidence I've seen so far.
