GPU buffers can be quite large, so userspace is expected to deal with allocation failure. Don't trigger the OOM killer when page allocation for the GEM objects fails, as this opens an easy possiblity for unprivileged applications to DOS the system,a s the shmem pages are not fully accounted to the allocating process.
