Hi Boris,

I reconsidered the situation.
If there is a non-recoverable mce as well, just let it print that reason. No need to bring the
timeout message indeed. Because since the tolerant was set to a high level to ignore the timeout,
we can eventually ignore them.

So simply drop cpu_missing variable as you mentioned should work.

I am not sure whether it should be authored by you or suggested by you.
Anyway, I will post a new patch exactly as you suggested. Please pick it or ignore it as appropriate :)

Thanks,
Zhaolong
