    parisc: PDT: Add full support for memory failure via Page Deallocation Table (PDT) · 54ac8fcb
    Helge Deller authored
    This patch adds full support to read PDT info on all machine types.  At bootup
    the PDT is read and bad memory excluded from usage via memblock_reserve().
    Later in the boot process a kernel thread is started (kpdtd) which regularily
    checks firmare for new reported bad memory and tries to soft offline pages in
    case of correctable errors and to kill processes and exclude such memory in
    case of uncorrectable errors via memory_failure().
