Hi Michael, First bad commit (maybe != root cause): tree: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git next-test head: 72cdd117c449896c707fc6cfe5b90978160697d0 commit: 231b232df8f67e7d37af01259c21f2a131c3911e [76/183] powerpc/64: Make VDSO32 track COMPAT on 64-bit config: powerpc-randconfig-r033-20201005 (attached as .config) compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project 1127662c6dc2a276839c75a42238b11a3ad00f32)
There has been already a discussion on this, see https://groups.google.com/g/clang-built-linux/c/ayNmi3HoNdY/m/ROdg7avVBwAJ
This apparently is a clang issue. The commit mentionned here is only exposing the issue, but the issue is not in the commit itself.
Regardless, this error should go away when we switch to the generic C VDSO. Christophe
