    Subject[PATCH 0/5] x86, NMI: give NMI handler a face-lift
    Restructuring the nmi handler to be more readable and simpler.

    This is just laying the ground work for future improvements in this area.

    I know people were complaining about having DIE_NMI and DIE_NMI_IPI, but
    for now it is consistent with what was there before. Hopefully, we can
    modify the notifier chain to make it smarter and combine the two events.

    I also left out one of Huang's patch until we figure out how we are going
    to proceed with a new notifier.

    Tested 32-bit and 64-bit on AMD and Intel machines.


    Huang Ying (5):
    x86, NMI: Add NMI symbol constants and rename memory parity to PCI
    x86, NMI: Add touch_nmi_watchdog to io_check_error delay
    x86, NMI: Rewrite NMI handler
    x86, NMI: Allow NMI reason io port (0x61) to be processed on any CPU
    x86, NMI: Remove do_nmi_callback logic
