Ingo, Is your desire to remove of the firmware callback/spinlock in hpwdt_pretimeout related to David Woodhouse patch set: https://lkml.org/lkml/2018/2/14/305 ? Which I think are to mitigate performance issues resulting from the changes to address the specter/meltdown? Any there other changes to hpwdt needed related to this work?
