Hmm, what kernel config caused that error?
It seems that the CONFIG_STACKTRACE is forced on if it is required.
And if you have found such case, IMHO, we should turn on the CONFIG_STACKTRACE
in Kconfig.
(Also, if it is not related to this series, it should be reported as a separated
bugfix :) )

Thank you,
