The MCE severity gives a hint as to how to handle the error. The notifier blocks can then use the severity to decide on an action. It's not necessary for machine_check_poll() to filter errors for the notifier chain, since each block will check its own set of conditions before handling an error. Also, there isn't any urgency for machine_check_poll() to make decisions based on severity like in do_machine_check(). If we can assume that a severity is set then we can use it in more notifier blocks. For example, the CEC block could check for a "KEEP" severity rather than checking bits in the status. This isn't possible now since the severity is not set except for "DEFFRRED/UCNA" errors with a valid address. Save the severity since we have it, and let the notifier blocks decide if they want to do anything.
