I should have known that 4.1-rc1 would show up just after I published my linux-next article, and here it is.. ftp://ftp.kernel.org/pub/linux/kernel/v4.x/testing/linux-4.1-rc1.tar.xz
$ uname -a Linux rg6830l 4.1.0-rc1 #1 SMP Sun Apr 26 18:56:05 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux
Brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/1504.3/01263.html
As with linux-next from April 24, the (patched) VMware 11.1.0 compiled and loaded OK, but the latest NVIDIA driver – 349.16 – failed:
FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol 'cpu_tss'
Some have suggested fixing these errors by simply editing the offending kernel code to disable the GPL-only rule, but this is in fact the wrong thing to do. Either the kernel development team makes the change, or NVIDIA has to change their code.
It is worth mentioning again that the VMware patch is still the one for Kernel 3.19 – which also works for kernel 4.0 and now 4.1.. Full instructions – and a copy of the patch – can be found at the excellent ArchLinux wiki: https://wiki.archlinux.org/index.php/VMware#3.19_kernels_and_up
