There appear to be some naming conflicts in the source code. I've been working with 6.0.2:

I found conflicts on 'uintptr_t', 'BIT_MASK', etc.

Also appears the 'autoconf' magic is not working for EPOLL and NICE.

After working around all of that, the kernel won't load the module due to an issue with 'pv_mmu_ops'. Believe the kernel guys are working that issue out.
