Kernel 4.18 has finally arrived, and details of changes since -rc8 are here: http://lkml.iu.edu/hypermail/linux/kernel/1808.1/02806.html
As expected, after changes in -rc7, the latest NVIDIA and (patched) VMware all compile/load OK.. Tested with VMware 14.1.2 with the vmmon patch, and NVIDIA 390.77 and 396.51.
Coincidentally, I can also confirm that 4.18 boots OK on HP PA-RISC (HP9000/785-C3700) – but more on that, in a later article..
