How recent do you think it needs to be? The machine I was testing on
yesterday is under a year old:
uname -m = ppc64le
uname -r = 4.18.19-100.fc27.ppc64le
uname -s = Linux
uname -v = #1 SMP Wed Nov 14 21:53:32 UTC 2018
The latest-by-version-number ppc64 kernel I can find in the buildfarm
is bonito,
uname -m = ppc64le
uname -r = 4.19.15-300.fc29.ppc64le
uname -s = Linux
uname -v = #1 SMP Mon Jan 14 16:21:04 UTC 2019
and that's certainly shown it too.
regards, tom lane
