Support for Kernel 4.12

Hi there!
I'm interested in getting this working with 3.2.15 and the Linux kernel 4.12 on Centos 7. My C++ is a bit stale, but wanted to share my experiences when attempting to compile your src under that environment.

Not sure if you have any plans to continue the development for the latest kernel, but you at least have one person who is out there, and interested!

Linux randomserver.localdomain 4.12.1-1.el7.elrepo.x86_64 #1 SMP Thu Jul 13 07:25:32 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux

This was the output as I attempted to build:
