Hi Christophe,
'struct ppc64_opd_entry' doesn't belong to uapi/asm/elf.h
It was initially in module_64.c and commit 2d291e902791 ("Fix compile
failure with non modular builds") moved it into asm/elf.h
But it was by mistake added outside of __KERNEL__ section,
therefore commit c3617f72036c ("UAPI: (Scripted) Disintegrate
arch/powerpc/include/asm") moved it to uapi/asm/elf.hAs Michael said on v1, I'm a little nervous about moving it out of uAPI after so long, although I do take the points of Arnd and Kees that we're not breaking compiled binaries, nor should people be using this struct to begin with... I've cc:ed the linux-api@ list. Kind regards, Daniel

Move it back into asm/elf.h, this brings it back in line with IA64 and PARISC architectures.
