  * Unmap a whole guest page if an MCE is encountered in it to avoid
    follow-on MCEs leading to the guest crashing, by Tony Luck.

    over the rebase.

  * AMD MCE error thresholding machinery cleanup and hotplug sanitization, by
    Thomas Gleixner.

  * Change the MCE notifiers to denote whether they have handled the error
    and not break the chain early by returning NOTIFY_STOP, thus giving the
    opportunity for the later handlers in the chain to see it. By Tony Luck.

  * Add AMD family 0x17, models 0x60-6f support, by Alexander Monakov.
