Subject: [PATCH] x86, MCE: eliminate the strange combination of return and break

What do you feel when you see the code snippet like that shown below?

        switch (c) {
        case X:
                ... ...
                return 1;
                break;
        case Y:
                ... ...
                return 1;
                break;
        }

All in all, in many ways I'm not feeling well. I think a small change
is needed here. This patch aims to eliminate the strange combination of
*return* and *break* in the above switch-statement.
