    Export shmem_file_setup for DRM-GEM
    
    GEM needs to create shmem files to back buffer objects.  Though currently
    creation of files for objects could have been driven from userland, the
    modesetting work will require allocation of buffer objects before userland
    is running, for boot-time message display.
