Hello all, After making a bunch of cleanups, I am stuck debating whether to continue updating this patch on the stale branch perf/nmi on Ingo's tree or just repost the whole patch again (which isn't much bigger just adds the arch/x86/kernel/apic/hw_nmi.c piece). Part of the new patch series includes removing kernel/nmi_watchdog.c, which seemed kinda silly because it was only an intermediate file until things got shifted to kernel/watchdog.c Thoughts?
