Generated files are also checked by sparse that's why add newline
to remove sparse (C=1) warning.

The issue was found on Microblaze and reported like this:
./arch/microblaze/include/generated/uapi/asm/unistd_32.h:438:45:
warning: no newline at end of file

Changes in v2:
- Update also others archs not just microblaze - Arnd
- Align subject and description to match multiarch chagne

Bummer, I had noticed that before
https://lore.kernel.org/lkml/CAMuHMdVsBwL9vcqejfc47GN793wMXdQ=SwEsSUP1fbpMt-OoWw@mail.gmail.com/
and even claimed I fixed it while applying
https://lore.kernel.org/lkml/CAMuHMdW6JiponxLiGNEXUX4xJk3hK4b8dTOCNvVBr7s2LyfhJw@mail.gmail.com/
but something must have gone wrong...

Why not add the "\n" to the end of the previous line?

Here there's already \n at the end, so no need for another one?

No it is not needed. But I think that make sense to have the same
solution in all these scripts. Above printf is adding newline that's why
I have used the same style.

I can drop m68k or align with with others. I would prefer to have the
same solution in all these scripts.

Yeah, it makes sense to align as much as possible.
IIRC, the original plan was to consolidate more later.

Note that all other lines are terminated with a "\n" at the end.
The separate 'printf "\n"' is an extra blank line, not the terminator for the
previous line.

Should we also get rid of 'printf "\n"' lines or just keep them as they
are today?

Usually there is a blank line above the include guard terminator, so IMHO
it makes sense to have that in generated files, too.

I meant more not to get rid of \n just include them in current prints.
It means like this 'printf "\n#endif /* %s */\n" "${fileguard}"'

I think having a "\n" at the start of a string makes the code harder to read.

You could move it to the end of the previous string, but that is not always
possible (e.g. after the loop), so I'd keep the separate prints for blank
lines.
