Merge tag 'mips_4.19_2' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
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
MIPS: Workaround GCC __builtin_unreachable reordering bug
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
