I can't say I'm wildly thrilled about the combinatorial explosion of
tunes that differ only in a few letters. Can't we just enable NEON and
VFPv4 under the existing cortex-a15 tune? Those ISAs are both part of
the Cortex-A15 cpu, right?

... this part of the commit message is superseded by the following
patch, right?
