When we copied it in v4.13, there was no such identifier.
The tag was added in v4.14
commit b24413180f5600bcb3bb70fbed5cf186b60864bd

License cleanup: add SPDX GPL-2.0 license identifier to files with
no license
So naive me checked COPYING and COPYING.new in v4.13 and spotted
The Linux Kernel is provided under:
SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
But as the tag was added in v4.14, GPL-2.0-only seems to be the right
thing to do I assume.
