Martin, FWIW, I created a signed tag to pull from. git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git tags/hlp_stage1 I have tested this tag and pull it into kvms390/next for the kvm related changes. As it contains a lot of s390/mm would be good if you could pull it too for 4.19. I have checked that linux/next can then merge kvms390/next+this and s390/features+this without a merge conflict.
