OK, as far as I can make out the patch does the right thing.
On Babbage 2.0 and the Pegatron lange5.1/nettop platforms, your check
is triggered, and at least on Babbage 2.0 /proc/cpuinfo and
/proc/self/auxv reflect the absence of NEON correctly. (I couldn't
boot to an fs on the Pegatron platform --- in any case I had to bodge
the machine ID passed by the bootloader to persuage the kernel to
boot).
On Babbage 3.0, NEON is reported as present in /proc/cpuinfo and
/proc/self/auxv.
See the attached logs.
Cheers
