Subject: Setting negative PANIC_TIMEOUT values not respected

despite there being existing defconfigs which specify negative values,
this channel does not actually appear to work, and the kernel behaves
as if the sign is being discarded. A PANIC_TIMEOUT=-1 reboots after a
second, not immediately.

https://bugzilla.kernel.org/show_bug.cgi?id=218574#c0

Hardcoding the value in situ works, passing it via defconfig not so
much. I assume the negative value code path is intended for
consumption :D

Yours sincerely,
Donald
