> Die or panic path in system reset handler dumps kernel log to
> nvram, since commit 4388c9b3a6ee ("powerpc: Do not send system
> reset request through the oops path") system reset request is
> not allowed to take die path if fadump or kdump is configured,
> hence we miss dumping kernel log to nvram, call kmsg_dump()
> before carrying out fadump or kdump.
