Hi Christophe, Thanks for this series. There are quite a few preliminary patches in it, before you get to the PPC part, which fix up general build system or test harness correctness issues. Since some of those affect all architectures that are adding vDSO getrandom() support for 6.12, I'm going to take those into my random.git tree as a fix for 6.11 now, in hopes that the new archs can mostly go into arch trees without too many tree interdependencies. So I'll reply to individual patches for that, mentioning which ones I extract. Jason
