  MIPS: Disable Loongson MMI instructions for kernel build (2019-10-10 11:58:52 -0700)

----------------------------------------------------------------
A few MIPS fixes for 5.4:

- Build fixes for CONFIG_OPTIMIZE_INLINING=y builds in which the
  compiler may choose not to inline __xchg() & __cmpxchg().

- A build fix for Loongson configurations with GCC 9.x.

- Expose some extra HWCAP bits to indicate support for various
  instruction set extensions to userland.

- Fix bad stack access in firmware handling code for old SNI
  RM200/300/400 machines.
