Will 5.0 have scheduler, reg alloc etc. bits for explicit support of AMD's 1st gen Zen (Ryzen, Epyc) arch? Is it safe to assume that the changes for Zen's 2nd gen will land prior to the hardware release, once the 1st gen is added? I think zen2 will arrive next year.

So there's more patches in the pipeline to land, then?
