Updated to Kernel 3.15-rc4 on my test system, and the latest VMware (10.0.2) and NVIDIA (337.12) still compile and run OK..

Brief details are here:  http://lkml.iu.edu//hypermail/linux/kernel/1405.0/01774.html

You will have to select the kernel.org versions of VMware modules, as the original VMware-supplied ones will not work..    See my original article at http://rglinuxtech.com/?p=1090
