you could try reverting most of our changes to this file and

added additional /proc/cpuinfo support that should make this

to update and see if this is the case.

I've confirmed that -mtune=native works fine at least for A53,
even if all the local changes to driver-aarch64.c is reverted.
I will commit it soon.

If we go this route, we should make the relevant procfs nodes independent
of -o linux.

that would be fine by me.

Nowadays, -o linux is turned on by default (unless nolinux is
specified explicitly). Still, native apps probably should not
depend on it.

This needs MI changes to procfs, not MD to aarch64. Should we
enable /proc/cpuinfo unconditionally?

i had to write the netbsd version of that code twice so far.
once for gcc 8.3 and 8.4, once for gcc 8.5 and 9.3, and i'd
really rather avoid having to write another version :)

Oh... Thank you very much for your hard works!
