Thanks, all.

I was pleased to hear many thought in active developer's mind.

I want to check some in MCA recovery.
Here is some steps, roughly say:

 - Stop whole system on MCA even if kernel not suffered.
 - Keep working except the suffered application.
 - Keep working, and give a chance to self-rehabilitation for the suffered
   application.

Just now, Linux is making an effort to step up the second from the first.

It also seems there are some key procedures, such as:

 - Specify process/thread(s) must be killed
 - Specify damaged resources (for example, poisoned pages)

To specify affected ones, OS requires:

 - Physical address (and if possible, Virtual address) of the offending
   operation.
 - Interruption must be synchronized.
 - States in registers when interrupted.

Is it wrong?
