commit 407984f2f65256dd81a95f18b03ab258a5b7aa42
Author: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>

    powerpc/mm: Catch the usage of cpu/mmu_has_feature before jump label init
    
    This enable us to catch the wrong usage of cpu_has_feature and
    mmu_has_feature in the code. We need to use the feature bit based
    check in show_regs because that is used in the reporting code.
