MIPS fixes for 5.0

[Paul Burton]

Hi Linus,

Here are a few late fixes it'd be great to squeeze into v5.0. They're
all pretty straightforward. Please pull.

Thanks,
    Paul

  MIPS: fix memory setup for platforms with PHYS_OFFSET != 0 (2019-02-27 18:49:29 -0800)

----------------------------------------------------------------
A few more MIPS fixes:

- Fix 16b cmpxchg() operations which could erroneously fail if bits 15:8
  of the old value are non-zero. In practice I'm not aware of any actual
  users of 16b cmpxchg() on MIPS, but this fixes the support for it was
  was introduced in v4.13.

- Provide a struct device to dma_alloc_coherent for Lantiq XWAY systems
  with a "Voice MIPS Macro Core" (VMMC) device.

- Provide DMA masks for BCM63xx ethernet devices, fixing a regression
  introduced in v4.19.

- Fix memblock reservation for the kernel when the system has a non-zero
  PHYS_OFFSET, correcting the memblock conversion performed in v4.20.
