For SEA exception, kernel require take some action to recover from memory
error, such as isolate poison page adn kill failure thread, which are done
in memory_failure().

During our test, the failure thread cannot be killed due to this issue[1],
Here, I temporarily workaround this issue by sending signals to user
processes in do_sea(). After [1] is merged, this patch can be rolled back
or the SIGBUS will be sent repeated.

What's the status of that one?  Seems better to help get that in than
carry this.
