* sysdeps/powerpc/powerpc64/dl-machine.h (elf_machine_runtime_setup): If profile != 0 does not anymore mean GLRO(dl_profile) != NULL. * sysdeps/powerpc/powerpc64/bits/link.h (struct la_ppc64_regs): Add padding. * sysdeps/powerpc/powerpc64/dl-trampoline.S: (_dl_profile_resolve): Extend _dl_prof_resolve to add pass extra parameters to _dl_profile_fixup and set up structure with register content.
