Log message:
        Explain pgd/pmd allocation failure strategies. Create a global 
bad-pmd-table,
        distinct from invalid-pmd-table for use during pmd allocation failure 
(so as
        to differentiate pgd_bad and pgd_none). The bad page table must have 
invalid
        pte entries to catch any user references to the range of virtual 
addresses
        it covers.
