Yazen has some cleanups to the severity code under consideration
here:

https://github.com/AMDESE/linux/commit/cf0b8a97240abf0fbd98a91cd8deb262f827721b


I wonder if a slightly different approach with the "mce_action" that Yazen
defines being a bitmask of options, instead of an enum, would be possible?

If that happened, then adding a "dump the call stack to the console" option
would fit neatly into the scheme.
