as a result of the changes that introduced:

WARNING: unmet direct dependencies detected for MDIO_OCTEON
  Depends on [n]: NETDEVICES [=y] && MDIO_DEVICE [=m] && MDIO_BUS [=m] && 64BIT && HAS_IOMEM [=y] && OF_MDIO [=m]
  Selected by [m]:
  - OCTEON_ETHERNET [=m] && STAGING [=y] && (CAVIUM_OCTEON_SOC && NETDEVICES [=y] || COMPILE_TEST [=y])

which is triggered by the staging OCTEON_ETHERNET driver which misses a
64BIT dependency but added COMPILE_TEST in 171a9bae68c72f2
(staging/octeon: Allow test build on !MIPS).
