Just installed Kernel 3.18-rc1 – released earlier than originally planned – on the test system:

$ uname -a
Linux rg6830l 3.18.0-rc1 #1 SMP PREEMPT Mon Oct 20 10:23:13 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/1410.2/01595.html

VMware 10.0.3 (with the vmnet patch..) installs and runs OK, but the latest current NVIDIA (340.46) fails to compile:
