Thank you for this. Going forward, I will start using randconfig as well to make
sure that I catch as many issues as I can.
For what concerns arm64 compat vdso, the compilation is currently disabled by
default when the compiler is clang, because there is a problem with the include
paths that requires further investigation. I was planning to provide a separate
patchset to address the problem.
