Kernel 5.1 is out, and brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/1905.0/03532.html
The latest NVIDIA driver (430.09) and patched VMware 15.0.4 both compile and run OK.
One odd quirk, is that the behaviour of
# make xconfig has changed, and if you have your custom configs saved out-of-tree, then the save option tries to save them back to the out-of-tree location again, rather than to the correct in-tree ~/.config file, as before.. Not sure this is a feature or bug, but it is certainly a nuisance!
