I was wondering... how do we inform userspace that this is available ?
Same question with adding the endian bit on 4xx which I plan to do using
your infrastructure...

We haven't defined a user-visible feature bit (and besides, we're really
getting short on these...). This is becoming a bit of concern btw (the
running out of bits). Maybe we should start defining an AT_HWCAP2 for
powerpc and get libc updated to pick it up ?
