For SEA exception, kernel require take some action to recover from memory

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.

That patch set has not been incorporated yet. The latest one is still
v11.

The consideration here was to ensure the functional integrity of
this feature. Considering that this may cause confusion, it is not
appropriate to make this temporary modification here. Otherwise, this
patch will not be included.  Related impacts are described in patch 0.

Thanks,
Tong.
