Piotr says lscpu isn't available on ppc FreeBSD. I think this leaves us with two

options:

1. either use sysctl with the risk that it may not return an
accurate value 2. not support PPC for numa detection

What do you think?

I think point #2 is more not supporting FreeBSD on PPC for numa
detection rather than not supporting PPC generally, right? Personally,
I am just in favour of #1 for the sake of moving forward and giving us
best support with simplest code. If or when someone does hit this
(FreeBSD+PPC) as a problem, then we can work with them to find best
solution for fixing it. Right now we don't have anyone with the
PPC+FreeBSD setup, so I'd rather ignore it than implement more
complicated solutions that we can't test "just in case".

+1, FreeBSD + PPC is not worth the complication

Thanks for the feedback, makes sense to me. I think v6 has all the features we want then - linux, windows and freebsd using sysctl.
