In the randconfig file:
# CONFIG_PPC_RADIX_MMU is not set
It is default y, but maybe that is not strong enough?
I.e., should it be selected by PPC_BOOK3S_64?
Changing the config to PPC_RADIX_MMU=y fixes the build errors.
Or should arch/powerpc/mm/book3s64/pgtable.c be modified to handle
the case of PPC_RADIX_MMU is not set?
thanks.
