Hi,
as I understand this, old kernels don't set the neon hwcap, while new
ones do on machines that support it.
If there are armv7 machines without neon (I don't know anything about
arm), wouldn't it make sense to trust HWCAP by default, so we get the
correct behaviour on new kernels? If there aren't, then why do we need
this conditional at all?
Thanks,
Julien
