Some functions defined in the intel-gtt module are used in several areas, but is only supported on x86 platforms. By separating these calls and their static underlying functions to another area, we are able to compile out these functions for non-x86 builds and provide stubs for the non-x86 implementations. In addition to the problematic calls, we are moving the gmch-related functions to the new area.
