It's basically any function call that was not inlined. It might even
be in a different kernel in the same module.

Recent mesa requires some kind of ICD loader to provide opencl. if
your distro uses ocl-icd package to provide ICD loader, you can use
OCL_ICD_VENDORS env var to select ICD drivers.

something like 'OCD_ICD_VENDORS=/var/empty' (any directory other than
/etc/OpenCL/vendors will do) effectively disables OpenCL by reporting
0 available platforms.
