Subject[GIT PULL] MIPS changes
Hi Linus,

Here are the main MIPS changes for 5.6. My apologies that they're coming
at the end of the week rather than the start, but there's nothing too
big or scary in here. Please pull.

There's one minor conflict with current master, in the DT
vendor-prefixes.yaml file. The correct resolution is of course to keep
both additions:

MIPS: PCI: Add detection of IOC3 on IO7, IO8, IO9 and Fuel (2020-01-24 11:37:45 -0800)

----------------------------------------------------------------
The main MIPS changes for 5.6:

- 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.
