Hello Christophe,
Thanks a lot for compiling the latest git kernel.
I have solved the compiling issue through setting up a value for the SUBLEVEL variable in
"a/Makefile". Before it wasn't necessary to set up a value for the SUBLEVEL variable.
I see, so it is a regression introduced by commit 9b82f13e7ef3 ("kbuild: clamp
SUBLEVEL to 255").
In the past there had already been such a regression at some point, which had then been fixed by
commit cacd54ef49b7 ("kbuild: Fix KERNELVERSION for empty SUBLEVEL or PATCHLEVEL")
Sasha, can you fix it ?
Thanks
Christophe
Cheers,
Christian

Hello,
I tried to compile the latest Git kernel today. Unfortunately it doesn't
compile.
I have no such problem with latest git kernel.

I have found the bad commit. It's "Merge tag 'kbuild-v5.12' of
git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild" [1]
The changes in the Makefile (a/Makefile) are responsible for the compiling
errors. [2]
I was able to revert this bad commit. After that it compiled without any
problems.
Could you please compile the latest Git kernel and confirm this issue?
Thanks,
Christian
