Pull MIPS fixes from Paul Burton:
 "A few MIPS fixes for 4.20:

   - Re-enable the Cavium Octeon USB driver in its defconfig after it
     was accidentally removed back in 4.14.

   - Have early memblock allocations be performed bottom-up to more
     closely match the behaviour we used to have with bootmem, which
     seems a safer choice since we've seen fallout from the change made
     in the 4.20 merge window.

   - Simplify max_low_pfn calculation in the NUMA code for the Loongson3
     and SGI IP27 platforms to both clean up the code & ensure
     max_low_pfn has been set appropriately before it is used"
