[PATCH v6 21/29] x86/nmi: Add an NMI_WATCHDOG NMI handler category

2022-05-05 Thread Ricardo Neri
Add a NMI_WATCHDOG as a new category of NMI handler. This new category is to be used with the HPET-based hardlockup detector. This detector does not have a direct way of checking if the HPET timer is the source of the NMI. Instead, it indirectly estimates it using the time-stamp counter.
