Pull MIPS fixes from Paul Burton:
"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"
