Merge tag 'mips_5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux

Pull MIPS changes from Paul Burton:
 "Nothing too big or scary in here:

   - Support mremap() for the VDSO, primarily to allow CRIU to restore
     the VDSO to its checkpointed location.

   - Restore the MIPS32 cBPF JIT, after having reverted the enablement
     of the eBPF JIT for MIPS32 systems in the 5.5 cycle.

   - Improve cop0 counter synchronization behaviour whilst onlining CPUs
     by running with interrupts disabled.

   - Better match FPU behaviour when emulating multiply-accumulate
     instructions on pre-r6 systems that implement IEEE754-2008 style
     MACs.

   - Loongson64 kernels now build using the MIPS64r2 ISA, allowing them
     to take advantage of instructions introduced by r2.

   - Support for the Ingenic X1000 SoC & the really nice little CU Neo
     development board that's using it.

   - Support for WMAC on GARDENA Smart Gateway devices.

   - Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in
     preparation for introducing IP35 (Origin 3*) support.

   - Various Kconfig & Makefile cleanups"
