Hi Linus,

Here is a collection of MIPS fixes for the 5.5 cycle; please pull.

Thanks,
    Paul

  MIPS: Avoid VDSO ABI breakage due to global register variable (2020-01-02 16:41:16 -0800)

----------------------------------------------------------------
A collection of MIPS fixes:

- Fill the struct cacheinfo shared_cpu_map field with sensible values,
  notably avoiding issues with perf which was unhappy in the absence of
  these values.

- A boot fix for Loongson 2E & 2F machines which was fallout from some
  refactoring performed this cycle.

- A Kconfig dependency fix for the Loongson CPU HWMon driver.

- A couple of VDSO fixes, ensuring gettimeofday() behaves appropriately
  for kernel configurations that don't include support for a clocksource
  the VDSO can use & fixing the calling convention for the n32 & n64
  VDSOs which would previously clobber the $gp/$28 register.

- A build fix for vmlinuz compressed images which were inappropriately
  building with -fsanitize-coverage despite not being part of the kernel
  proper, then failing to link due to the missing
  __sanitizer_cov_trace_pc() function.

- A couple of eBPF JIT fixes, including disabling it for MIPS32 due to a
  large number of issues with the code generated there & reflecting ISA
  dependencies in Kconfig to enforce that systems which don't support
  the JIT must include the interpreter.
