Awesome!

What machines are they? Maybe they are Power4+ ?

I asked 1 year ago if anyone was using Power4, and got no responses:

  https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/156213.html

I realise you probably don't follow the mailing list, perhaps I should
have Cc'ed debian-powerpc or some other lists.

Anyway if you are actually using mainline on a Power4 then we can re-add
support for it, if you are willing to test it, because I have no Power4
machines to test on.

Yes I'm aware of that, I have several Freescale machines which are part
of my continuous-integration setup.
