Kernel 4.20-rc1 is out, and brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/1811.0/02531.html

VMware 15.0 installs OK, but the latest NVIDIA fails.. (410.73 with the pm patch, if needed):

........................
/home/rgadsdon/kernel/NVIDIA-Linux-x86_64-410.73-custom/kernel/nvidia/linux_nvswitch.c:1582:5: error: implicit declaration of function ‘time_to_tm’; did you mean ‘time64_to_tm’? [-Werror=implicit-function-declaration]
time_to_tm(time_nsec / NVSWITCH_NSEC_PER_SEC, 0, &t);
^~~~~~~~~~
time64_to_tm
.....................

I made the change to linux_nvswitch.c, and then:

............................
/home/rgadsdon/kernel/NVIDIA-Linux-x86_64-410.73-custom/kernel/nvidia-drm/nvidia-drm-gem-nvkms-memory.c:348:11: error: implicit declaration of function ‘vm_insert_pfn’; did you mean ‘vmf_insert_pfn’? [-Werror=implicit-function-declaration]
ret = vm_insert_pfn(vma, address, pfn + page_offset);
^~~~~~~~~~~~~
vmf_insert_pfn
...........................

Made that change, as well, and then the driver compiled/loaded OK:

But…   the compilation threw a lot of repeated ‘warnings’:

More testing will be needed!
