Sorry, I'm doing a bug scrub and found https://github.com/ClangBuiltLinux/linux/issues/774 still open (and my reply to this thread still in Drafts; never sent). With my patches rebased: $ file arch/powerpc/kernel/vdso32/vdso32.so arch/powerpc/kernel/vdso32/vdso32.so: ELF 32-bit MSB shared object, PowerPC or cisco 4500, version 1 (SYSV), dynamically linked, stripped Are you still using 2.26? I'm not able to repro Nathan's reported issue from https://lore.kernel.org/lkml/20200902052123.GA2687902@ubuntu-n2-xlarge-x86/, so I'm curious if I should resend the rebased patches as v2? -- Thanks, ~Nick Desaulniers
