Fix compile errors when CONFIG_ARCH_WANT_OPTIMIZE_DAX_VMEMMAP=n
I don't understand your patch.
As far as I can see, CONFIG_ARCH_WANT_OPTIMIZE_DAX_VMEMMAP is selected
when CONFIG_PPC_RADIX_MMU is selected, and radix_pgtable.o is built only
when CONFIG_PPC_RADIX_MMU is selected. So when radix_pgtable.o is built
CONFIG_ARCH_WANT_OPTIMIZE_DAX_VMEMMAP will always be selected.
Can you clarify what the problem is ?
