#      "A couple more MIPS fixes for 4.18:
#     
#        - Fix an off-by-one in reporting PCI resource sizes to userland which
#          regressed in v3.12.
#     
#        - Fix writes to DDR controller registers used to flush write buffers,
#          which regressed with some refactoring in v4.2"
