Overflow mitigation"), so adding in Borislav.

Thanks for the report. We're tracking this here
https://github.com/ClangBuiltLinux/linux/issues/1907
It was pointed out that PeterZ has a series reworking this code entirely:

That's troubling if stable is already picking up patches that are
breaking the build!

As I pointed out in that issue, I don't think that series helps us with
this issue but I will try to test shortly (the patches did not apply
cleanly but I have not looked into why yet).

Those patches are already released in stable, they were basically
released at the same time as they were merged into mainline:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-6.4.y
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-6.1.y
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-5.15.y
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-5.10.y
