    m68k: add TIF_NOTIFY_RESUME and handle it. · a54f1655
    Al Viro authored
    TIF_NOTIFY_RESUME added (as bit 5).  That way nommu glue needs no changes at
    all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return
    There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead
    of checking that MSBit is set (jmi) we check that MSBit or something below it
    is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is
    set".
    
    Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue
    calls it instead of do_signal().
