[igt-dev] [PATCH i-g-t] lib/ioctl_wrappers: Delete gem_total_mappable_size()

[Ashutosh Dixit]

gem_total_mappable_size() has no callers and calls the
DRM_I915_GEM_GET_APERTURE ioctl using 'struct
local_i915_gem_get_aperture' which has fields which are unsupported in
the kernel. Delete the function.
