Moving to Linux Kernel 5.0

[Joel Stanley]

Hello,

It's been a few releases since we bumped, so I'm going to publish a
5.0 based tree this week. I've done some testing on the machine I have
(OpenPower Romulus ast2500) and it looks good.

I'll be rebasing without discarding patches for this release. That
means if you have non-mainline patches it will still be there for
dev-5.0. Next release we will do a cleanout, so please ensure your out
of tree patches are on the upstream lists for 5.2 now.

Cheers,

Joel
