From: Chris Metcalf <cmetcalf@xxxxxxxxxx> These changes allow the watchdog to work cleanly with nohz_full by default, and to be configurable if desired to enable the watchdog on cores that would normally disable it due to being nohz_full. Thomas, does the addition of an exclude_mask to smp_hotplug_thread meet with your approval? It seems like a pretty clean extension and enables the desired watchdog functionality for nohz_full pretty nicely, I think. Uli, this version is based on the linux-next tree, which includes your recent refactoring changes; I've made all your suggested changes. Don and/or Uli, do you want to give your Acked-by to the watchdog change? Frederick, I guess you could push it through your nohz tree? Or would it make sense for Andrew to take this into his tree, which looks like what happened with Uli/Don's earlier watchdog changes? I'm assuming my pushing it through the arch/tile tree is probably not the best way to go.
