Subject[GIT PULL] MIPS fixes for 5.0
Hi Linus,

Here's a batch of MIPS fixes for 5.0; my apologies that these have built
up over a few busy weeks. Please pull.

mips: cm: reprime error cause (2019-02-07 11:55:24 -0800)

A batch of MIPS fixes for 5.0, nothing too scary.

- A workaround for a Loongson 3 CPU bug is the biggest change, but
still fairly straightforward. It adds extra memory barriers (sync
instructions) around atomics to avoid a CPU bug that can break

- Loongson64 also sees a fix for powering off some systems which would
incorrectly reboot rather than waiting for the power down sequence to

- We have DT fixes for the Ingenic JZ4740 SoC & the JZ4780-based Ci20
board, and a DT warning fix for the Nexsys4/MIPSfpga board.

- The Cavium Octeon platform sees a further fix to the behaviour of the
pcie_disable command line argument that was introduced in v3.3.

- The VDSO, introduced in v4.4, sees build fixes for configurations of
GCC that were built using the --with-fp-32= flag to specify a default
32-bit floating point ABI.

- get_frame_info() sees a fix for configurations with
CONFIG_KALLSYMS=n, for which it previously always returned an error.

- If the MIPS Coherence Manager (CM) reports an error then we'll now
clear that error correctly so that the GCR_ERROR_CAUSE register will
be updated with information about any future errors.
