Title:
Missing export symbol for mtrr_add and mtrr_del
Status in linux package in Ubuntu:
Incomplete
Bug description:
I try to use the 4.4 Kernel from the ppa git.
So if i complie the current fglrx driver all is fine but on modules
load i get the error that the symbols
mtrr_del
mtrr_add
are missing.
I saw a patch for 4.3 for Nvidia facing the same issue.
Could you integrate the patch in the kernel ?
Here is the patch for
