Perhaps it's better to stick to a single SPDX version style for
all kernel files.

Right now, there are already several -only and -or-later uses.

$ git grep -P 'SPDX-License-Identifier.*(?:-or-later|-only)'| wc -l
144

So perhaps a patch and a tool to do the reverse conversion:

No.  Any tool which does anything useful just has to understand both
2.0 and 3.0 naming.  They're aliases for each other, that's all.

But that same tool would have to be updated if ever
yet-another spdx version appears.

So it'd probably be better to support just 1 version.
