[PATCH v5 14/18] watchdog/hardlockup: detect hard lockups using secondary (buddy) CPUs

2023-05-19 Thread Douglas Anderson
Implement a hardlockup detector that doesn't doesn't need any extra arch-specific support code to detect lockups. Instead of using something arch-specific we will use the buddy system, where each CPU watches out for another one. Specifically, each CPU will use its softlockup hrtimer to check that
