While this is a good idea, note there may be still poisoned lines
in memory that haven't resulted in a machine check yet, but could
still be fatal when read after a full crash dump for some other
reason.

So you still need

http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commit;h=fe61906edce9e70d02481a77a617ba1397573dce
and
http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commit;h=cb58f049ae6709ddbab71be199390dc6852018cd

in addition.
