    PPC update for the recent changes to the pgd/pmd/pte functions. · 36f581c6
    Paul Mackerras authored
    This implements ptes-in-highmem for PPC, removes the quicklist
    and zero-page stuff.  PTEs in highmem on SMP turned out to need
    some significant changes to avoid deadlocks on the hash_table_lock
    (now renamed to mmu_hash_lock).  The PMDs now contain the physical
    address of the PTE page rather than the virtual address.
    Anything that takes the mmu_hash_lock now operates with the DMMU
    off to avoid MMU hash-table misses.
