Probably also related to "make headers-install":

https://lkml.kernel.org/r/20231209020144.244759-1-jhubbard@nvidia.com

The general problem is that some mm selftests are currently not written 
in way that allows them to compile with old linux headers. That's why 
the build fails if "make headers-install" was not executed, but it does 
not fail if "make headers-install" was once upon a time executed, but 
the headers are outdated.
