I think Sasha's patch here: https://lore.kernel.org/r/20210205174702.1904681-1-sashal@kernel.org is looking like the solution.

It might cause trouble to those forcing SUBLEVEL to a given version such as .0 to avoid exposing the exact stable version. I guess we should instead try to integrate a test on the value itself and cap it at 255.

Something like this looks more robust to me, it will use SUBLEVEL for values 0 to 255 and 255 for any larger value:

- expr $(VERSION) * 65536 + 0$(PATCHLEVEL) * 256 + 0$(SUBLEVEL)); \ + expr $(VERSION) * 65536 + 0$(PATCHLEVEL) * 256 + 255 * (0$(SUBLEVEL) > 255) + 0$(SUBLEVEL) * (0$(SUBLEVEL <= 255)); \
