    powerpc/64s: Add workaround for P9 vector CI load issue
    
    POWER9 DD2.1 and earlier has an issue where some cache inhibited
    vector load will return bad data. The workaround is two part, one
    firmware/microcode part triggers HMI interrupts when hitting such
    loads, the other part is this patch which then emulates the
    instructions in Linux.
    
    The affected instructions are limited to lxvd2x, lxvw4x, lxvb16x and
    lxvh8x.
    
    When an instruction triggers the HMI, all threads in the core will be
    sent to the HMI handler, not just the one running the vector load.
    
    In general, these spurious HMIs are detected by the emulation code and
    we just return back to the running process. Unfortunately, if a
    spurious interrupt occurs on a vector load that's to normal memory we
    have no way to detect that it's spurious (unless we walk the page
    tables, which is very expensive). In this case we emulate the load but
    we need do so using a vector load itself to ensure 128bit atomicity is
    preserved.
    
    Some additional debugfs emulated instruction counters are added also.
