Merge tag 'mips_5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS updates from Paul Burton:

 - Support for the MIPSr6 MemoryMapID register & Global INValidate TLB
   (GINVT) instructions, allowing for more efficient TLB maintenance
   when running on a CPU such as the I6500 that supports these.

 - Enable huge page support for MIPS64r6.

 - Optimize post-DMA cache sync by removing that code entirely for
   kernel configurations in which we know it won't be needed.

 - The number of pages allocated for interrupt stacks is now calculated
   correctly, where before we would wastefully allocate too much memory
   in some configurations.

 - The ath79 platform migrates to devicetree.

 - The bcm47xx platform sees fixes for the Buffalo WHR-G54S board.

 - The ingenic/jz4740 platform gains support for appended devicetrees.

 - The cavium_octeon, lantiq, loongson32 & sgi-ip27 platforms all see
   cleanups as do various pieces of core architecture code.
