The feature was never merged and there has been no progress in the
last year. The wrappers are using a wrong ioctl number (38 is
HAS_POOLED_EU and not CREATE_VERSION) and extensions of the
gem_create and get_aperture ioctl structures that never made it into
the kernel.
Tests that were using the wrappers have already been removed by previous
patches so it is now safe to remove the wrappers themselves.
