This breaks microwatt_defconfig, which does not enable CONFIG_PPC_64S_HASH_MMU:
../arch/powerpc/mm/book3s64/radix_pgtable.c: In function ‘radix__early_init_mmu’:
../arch/powerpc/mm/book3s64/radix_pgtable.c:601:27: error: lvalue required as left operand of assignment
601 | mmu_virtual_psize = MMU_PAGE_4K;

Because mmu_virtual_psize is defined in hash_utils.c, which isn't built.
cheers
