This patch adds an early NMI counter and exports it trough /proc/interrupts with the name of ENM (Early NMI).For a userspace interface I suspect we just want to dump the count into the NMI counter. It probably makes sense to have a separate variable in early boot like you do, but then about the time we setup the normal NMI handler move the NMI count over and possibly do something like reboot if that is our policy.
I am fine with either approach. I guess that is the x86 maintainers' call. Ingo, Thomas, Peter, what do you think? Should I add a new entry to /proc/interrupts or move over the early NMI count to the existing per-cpu NMI counter?
