Description: Disable MTRR on kernel >= 4.3
|
|
From kernel 4.3 and newer (commit 2baa891e42d84) mtrr_add and mtrr_del are no
|
|
longer exported. The Nvidia kernel shim still uses it as of 304.131, causing
|
|
the module to error out when loading. Disable MTRR if running on 4.3 or greater
|
|
until upstream fixes it.
