        src/common/lib/libc/arch/mips/atomic: atomic_add.S atomic_and.S
            atomic_dec.S atomic_inc.S atomic_or.S atomic_swap.S
        src/common/lib/libc/arch/mips/string: bcopy.S

        src/sys/arch/mips/mips: lock_stubs_ras.S mipsX_subr.S mips_fixup.c

Log Message:
loongson2f support:
- Add some loongson2 definitions to cpuregs.h, from OpenBSD
- Make sure that the at register is useable before every jump register
  instruction (exept when register is k0 or k1) because -mfix-loongson2f-btb
  needs the at register for its workaround
- add code to mips_fixup.c to handle the instructions added by
  -mfix-loongson2f-btb
- Add a ls2-specific tlb miss handler: it doesn't have separate handler
  for the xtlbmiss exeption.
- Fixes for some #ifdef MIPS3_LOONGSON2 assembly code (using the wrong
  register)
