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"
