Merge tag 'mips_fixes_5.4_1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS fixes from Paul Burton:

 - Build fixes for Cavium Octeon & PMC-Sierra MSP systems, as well as
   all pre-MIPSr6 configurations built with binutils < 2.25.

 - Boot fixes for 64-bit Loongson systems & SGI IP28 systems.

 - Wire up the new clone3 syscall.

 - Clean ups for a few build-time warnings.
