[304.132] nvidia.ko: Unknown symbol in module

Installer compiled the kernel module, but kernel can’t load nvidia.ko.

$ uanme -r

Among other stuff, logs have this:
[ 98.303677] nvidia: Unknown symbol mtrr_del (err 0)
[ 98.303902] nvidia: Unknown symbol mtrr_add (err 0)

nVidia still didn’t fix theirs drivers (MTRR stuff). :(
Why do i have to backport obsolete stuff into kernel to make it (nvidia driver) work? I’ll just stay with nouveau instead.
