nVidia kernel module fails to load since kernel 3.16: missing mtrr symbols

Hello everyone. I haven’t been able to install the nVidia drivers since kernel 3.16. I get messages in dmesg like this:

nvidia: Unknown symbol mtrr_del (err 0)

I will attach some logs soon.

In this case I used the Liquorix kernel but it fails with the distro kernel too of course.
