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

Reviewed-by: Nicholas Piggin <npiggin@gmail.com> I wonder if we should add that third entry, just for completeness. And 'r2' isn't a good name should probably be toc. And should it be packed? At any rate that's not for your series, a cleanup I might think about for later. Thanks, Nick
