In this patchset, we remove the unused macro EX_TYPE_COPY and centralize
the processing of memory-failure to do_machine_check() to avoid calling
memory_failure_queue() separately for different MC-Safe scenarios. In
addition, MCE_IN_KERNEL_COPYIN is renamed MCE_IN_KERNEL_COPY_MC to expand
its usage scope.
The patchset is a followup[1], as Borislav suggested[2], we firstly
cleanup unused EX_TYPE_COPY, then rename MCE_IN_KERNEL_COPYIN to
reduce confusion, could you give us some comments about it,
many thanks.
