    parisc: Add Page Deallocation Table (PDT) support · c9c2877d
    Helge Deller authored
    The firmare in most parisc machines maintains a Page Deallocation Table (PDT)
    which holds a list of physical memory addresses where hardware detected memory
    errors (single bit and double bit errors).
    This patch adds the missing PDC firmware calls and the logic to read the PDT
    from firmware, report all current PDT entries and exclude the reported bad
    memory from being used by Linux.
