Thanks – again – to mkubecek, there is now a fix for VMware 14.0.0 and Kernel 4.15 – and details are here:   https://github.com/mkubecek/vmware-host-modules/commit/562121d7bc06

The fix involves changes to vmmon-only/linux/driver.c and vmmon-only/linux/hostif.c, and a new file: vmmon-only/include/compat_timer.h .    I have tested this on 4.15-rc1, and now vmmon compiles, and vmware loads/runs, correctly.
