* elf/dl-runtime.c (reloc_offset): Define.
	(reloc_index): Define.
	(_dl_fixup): Rename reloc_offset parameter to reloc_arg.
	(_dl_fixup_profile): Likewise.  Use reloc_index instead of
	computing index from reloc_offset.
	(_dl_call_pltexit): Likewise.
	* sysdeps/x86_64/dl-trampoline.S (_dl_runtime_resolve): Just pass
	the relocation index to _dl_fixup.
	(_dl_runtime_profile): Likewise for _dl_fixup_profile and
	_dl_call_pltexit.
	* sysdeps/x86_64/dl-runtime.c: New file.

+/* The ABI calls for the PLT stubs to pass the index of the relocation
+   and not its offset.  In _dl_profile_fixup and _dl_call_pltexit we
+   also use the index.  Therefore it is wasteful to compute the offset
+   in the trampoline just to reverse the operation immediately
+   afterwards.  */
