Peter, this solves the issue you reported previously [1].

Agreed, thanks.  I'll also add the POWER9 support to the GCC side
of the patch now that the glibc code is upstream.

I do not see these bits being added in kernel side yet and GLIBC usual
only sync these kind of bits *after* they are included in kernel side.
So I would advise to either get these pieces (kernel support and hwcap
advertise) in kernel before 2.23 release, otherwise revert the patches.

Ack.
It has just been sent to the correspondent Linux mailing list:
https://lists.ozlabs.org/pipermail/linuxppc-dev/2016-January/137763.html

Please revert the changes from glibc until you checkin support to linux
kernel mainline.

Leaving these bits in increases the risk that someone uses to deploy a glibc
that then may have the wrong value.

Cheers,
Carlos.
