    Pull MIPS fixes from Paul Burton:
    
      - Fix microMIPS build failures by adding a .insn directive to the
        barrier_before_unreachable() asm statement in order to convince the
        toolchain that the asm statement is a valid branch target rather
        than a bogus attempt to switch ISA.
    
      - Clean up our declarations of TLB functions that we overwrite with
        generated code in order to prevent the compiler making assumptions
        about alignment that cause microMIPS kernels built with GCC 7 &
        above to die early during boot.
    
      - Fix up a regression for MIPS32 kernels which slipped into the main
        MIPS pull for 4.19, causing CONFIG_32BIT=y kernels to contain
        inappropriate MIPS64 instructions.
    
      - Extend our existing workaround for MIPSr6 builds that end up using
        the __multi3 intrinsic to GCC 7 & below, rather than just GCC 7.
    
    * tag 'mips_4.19_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux:
      MIPS: lib: Provide MIPS64r6 __multi3() for GCC < 7

      compiler.h: Allow arch-specific asm/compiler.h
      MIPS: Avoid move psuedo-instruction whilst using MIPS_ISA_LEVEL
      MIPS: Consistently declare TLB functions
      MIPS: Export tlbmiss_handler_setup_pgd near its definition
