The clone3 bug has been around for ages, it's probably not even that hard to fix and just needs a little bit of testing. If anyone wants to work on the time64 support for the vdso, I can explain the details for how it's done. Both of these are real bugs that should be addressed, unlike the other warning fixes that are mostly cosmetic aside from allowing the build with CONFIG_WERROR=y. Arnd
