* elfxx-mips.c (mips_got_info): Add a "reloc_only_gotno" field.
(mips_elf_got_section): Delete.
(mips_elf_sort_hash_table): Use g->reloc_only_gotno to decide
how many reloc-only entries there are.
(mips_elf_count_got_symbols): Adjust g->reloc_only_gotno as
well as g->global_gotno.
(mips_elf_make_got_per_bfd): Initialize reloc_only_gotno.
(mips_elf_multi_got): Likewise. Use gg->reloc_only_gotno
rather than gg->assigned_gotno to store the number of
reloc-only GOT entries.
(mips_elf_create_got_section): Remove the MAYBE_EXCLUDE parameter.
Initialize reloc_only_gotno.
(mips_elf_calculate_relocation): Check htab->got_info instead of
dynobj when deciding whether to call mips_elf_adjust_gp,
(_bfd_mips_elf_create_dynamic_sections): Adjust the call
to mips_elf_create_got_section.
(mips_elf_record_relocs): Likewise. Remove redundant
"dynobj == NULL" code. Do not use mips_elf_create_got_section
or mips_elf_record_global_got_symbol for R_MIPS_32, R_MIPS_REL32
and R_MIPS_64; limit global_got_area to GGA_RELOC_ONLY instead.
(_bfd_mips_elf_finish_dynamic_symbol): Use htab->sgot instead
of mips_elf_got_section.
(_bfd_mips_vxworks_finish_dynamic_symbol): Likewise.
(_bfd_mips_elf_finish_dynamic_sections): Likewise.
Move the initial assignment of G to the block that uses it;
it is used for an unrelated purpose later.

* ld-mips-elf/tls-hidden4.got, ld-mips-elf/tls-hidden4.r: We have
removed an unused GOT entry that was allocated for the R_MIPS_32
relocation against "undef", so adjust addresses down by 4 bytes.
* ld-mips-elf/got-dump-1.d, ld-mips-elf/got-dump-2.d: We have
changed the order of the GOT entries so that reloc-only ones
come last. "undef" is only referred to by dynamic relocations,
so it now comes after "glob".
* ld-mips-elf/mips16-pic-2.dd, ld-mips-elf/mips16-pic-2.gd,
ld-mips-elf/mips16-pic-2.nd, ld-mips-elf/mips16-pic-2.rd: We have
removed two unused local GOT entries that were originally created
as global entries for the hidden symbols "used2" and "used3".
"used4" and "used5" are only referred to by relocations, so they
now come after "used6" and "used7".

* elfxx-mips.c (mips_got_page_range): New structure.
(mips_got_page_entry): Likewise.
(mips_got_info): Add page_gotno and got_page_entries fields.
(mips_elf_got_per_bfd_arg): Add max_pages field. Delete
primary_count and current_count fields.
(mips_got_page_entry_hash, mips_got_page_entry_eq): New functions.
(mips_elf_pages_for_range, mips_elf_record_got_page_entry): Likewise.
(mips_elf_get_got_for_bfd): New function, split out from
mips_elf_make_got_per_bfd. Initialize the page_gotno and
got_page_entries fields when creating a new GOT structure.
(mips_elf_make_got_pages_per_bfd): New function.
(mips_elf_merge_got_with): New function, split out from
mips_elf_make_got_per_bfd. Merge page entries as well as
non-page entries. Use the minimum of max_pages and the sum
of the page_gotnos to estimate the number of page entries.
(mips_elf_merge_gots): Use the minimum of max_pages and the
bfd's page_gotno to estimate the number of page entries.
Use the above functions.
(mips_elf_multi_got): Add page entries as well as non-page entries
to the individual per-bfd GOTs. Initialize got_per_bfd_arg.max_pages.
Initialize the page_gotno and got_page_entries fields when creating
a new primary GOT. Use the minimum of pages and page_gotno when
adding the number of pages entries to local_gotno.
(mips_elf_create_got_section): Initialize the page_gotno and
got_page_entries fields of the GOT structure.
(mips_elf_rel_relocation_p, mips_elf_read_rel_addend)
(mips_elf_add_lo16_rel_addend, mips_elf_get_section_contents): New
functions, split out from...
(_bfd_mips_elf_relocate_section): ...here.
(_bfd_mips_elf_check_relocs): Record GOT page entries too.
(_bfd_mips_relax_section): Use mips_elf_get_section_contents.
(_bfd_mips_elf_always_size_sections): Use the smaller of the
loadable_size- and page_gotno-derived estimates.
