This warning can be seen in allyesconfig, and was introduced by commit
f9eb581c63b2acce827570e105205c0789360650 "powerpc: fix build of
epapr_paravirt on 64-bit book3s".

Sorry about the churn on this -- I did try to build allyesconfig, but I
forgot that CONFIG_PPC_DISABLE_WERROR would be enabled, plus the build
failed on the "attempt to move .org backwards" issue.
