+ /* Ensure a CMCI interrupt can't preempt this. */ + local_irq_save(flags); if (mce_available(__this_cpu_ptr(&cpu_info))) { machine_check_poll(MCP_TIMESTAMP, &__get_cpu_var(mce_poll_banks));
Does this remove the problem that you fixed in part4? If a CMCI can no longer interrupt a poll ... do we really need the locks you added?
