ACPI, APEI, Printk queued error record before panic
Because printk is not safe inside NMI handler, the recoverable error
records received in NMI handler will be queued to be printked in a
delayed IRQ context via irq_work. If a fatal error occurs after the
recoverable error and before the irq_work processed, we lost a error
report.
To solve the issue, the queued error records are printked in NMI
handler if system will go panic.
