Interesting patches, thanks for looking into it. I don't know much
about compat and wrong endian userspaces. I think sys_switch_endian
is enabled though, it's just a strange fast endian swap thing that
has been disabled by default.

The first patches look pretty good. Maybe for the last one it could
become a selectable option?

It's for 32-bit userspace only. Can we just get rid of it, or is
there some old broken 64-bit BE userspace that tries to call it?

Thanks,
Nick
