bfd/
* elfxx-mips.c (print_mips_ases): Add Loongson EXT2 extension.
binutils/
* readelf.c (print_mips_ases): Add Loongson EXT2 extension.
gas/
* NEWS: Mention Loongson EXTensions R2 (EXT2) support.

.set loongson-ext2 and .set noloongson-ext2.
* testsuite/gas/mips/loongson-ext2.d: New test.
* testsuite/gas/mips/loongson-ext2.s: New test.
* testsuite/gas/mips/mips.exp: Run loongson-ext2 test.
include/
* elf/mips.h (AFL_ASE_LOONGSON_EXT2): New macro.
(AFL_ASE_MASK): Update to include AFL_ASE_LOONGSON_EXT2.
* opcode/mips.h (ASE_LOONGSON_EXT2): New macro.
opcodes/
* mips-dis.c (parse_mips_ase_option): Handle -M loongson-ext
option.
