* elf32-mips.c (elf_mips_howto_table_rel): Replace all uses of
	mips_elf_generic_reloc with _bfd_mips_elf_generic_reloc.  Use
	_bfd_mips_elf_hi16_reloc for R_MIPS_HI16 and R_MIPS_GNU_REL_HI16,
	_bfd_mips_elf_lo16_reloc for R_MIPS_LO16 and R_MIPS_GNU_REL_LO16,
	and _bfd_mips_elf_got16_reloc for R_MIPS_GOT16.  Change rightshift
	to 16 for R_MIPS_HI16 and R_MIPS_GNU_REL_HI16.
	(mips_elf_generic_reloc, struct mips_hi16, mips_elf_hi16_reloc)
	(mips_elf_lo16_reloc, mips_elf_got16_reloc): Delete.
	(_bfd_mips_elf32_gprel16_reloc): Remove special case.
	(mips_elf_gprel32_reloc, mips32_64bit_reloc): Likewise.

	* elf64-mips.c (mips_elf64_howto_table_rel): Replace all uses of
	mips_elf_generic_reloc with _bfd_mips_elf_generic_reloc.  Use
	_bfd_mips_elf_hi16_reloc for R_MIPS_HI16, _bfd_mips_elf_lo16_reloc
	for R_MIPS_LO16 and _bfd_mips_elf_got16_reloc for R_MIPS_GOT16.
	Change R_MIPS_HI16's rightshift to 16.
	(mips_elf64_howto_table_rela): Replace all uses of
	mips_elf_generic_reloc with _bfd_mips_elf_generic_reloc.
	Use _bfd_mips_elf_generic_reloc for R_MIPS_GOT16 as well.
	(mips_elf64_hi16_reloc, mips_elf64_got16_reloc): Delete.
	(mips_elf64_shift6_reloc): Remove special case.  Use
	_bfd_mips_elf_generic_reloc instead of returning bfd_reloc_continue.

	* elfn32-mips.c (prev_reloc_section): Delete.
	(prev_reloc_address, prev_reloc_addend): Delete.
	(elf_mips_howto_table_rel, elf_mips_howto_table_rela): As for
	elf64-mips.c
	(GET_RELOC_ADDEND, SET_RELOC_ADDEND): Delete.
	(mips_elf_generic_reloc, struct mips_hi16, mips_elf_hi16_reloc)
	(mips_elf_lo16_reloc, mips_elf_got16_reloc): Delete.
	(mips_elf_gprel16_reloc): Delete use of GET_RELOC_ADDEND.
	(mips_elf_literal_reloc, mips_elf_gprel32_reloc): Likewise.
	(mips16_jump_reloc, mips16_gprel_reloc): Likewise.
	(mips_elf_shift6_reloc): Likewise.  Delete use of SET_RELOC_ADDEND.

	* elfxx-mips.c (_bfd_mips_elf_gprel16_with_gp): Use
	_bfd_relocate_contents to install an in-place addend.
	(mips_hi16): New structure.
	(mips_hi16_list): Moved from elf32-mips.c.
	(_bfd_mips_elf_hi16_reloc, _bfd_mips_elf_got16_reloc): New functions.
	(_bfd_mips_elf_lo16_reloc, _bfd_mips_elf_generic_reloc): New functions.
	(mips_elf_calculate_relocation): Assume addend is unshifted.
	(_bfd_mips_elf_relocate_section): Don't apply the howto rightshift
	on top of the usual high-part shift.  Don't shift the addend right
	before calling mips_elf_calculate_relocation.

	* elfxx-mips.h (_bfd_mips_elf_hi16_reloc): Declare.
	(_bfd_mips_elf_got16_reloc, _bfd_mips_elf_lo16_reloc): Declare.
	(_bfd_mips_elf_generic_reloc): Declare.

gas/
	* config/tc-mips.c (mips_need_elf_addend_fixup): Delete.
	(md_apply_fix3): Remove bfd_install_relocation workarounds.
	(tc_gen_reloc): Likewise. Factor handling of pc-relative relocations
	and treat fx_addnumber as relative to the relocation address.

gas/testsuite/
	* gas/mips/mips16-jalx.d: Use -mabi=o64.
	* gas/mips/mips16.d: Likewise.
	* gas/mips/elf-rel17.[sd]: New test.
	* gas/mips/mips.exp: Run it.
