Does the early console output something once it's initialized? If not
then I'd go one step further here: if early_printk serial debugging was
configured, let's output some sort of message as early as it's expected
to work. That way if any of this debug codepath regresses for
relocate_kernel, the discovery of that regression won't be delayed
until something nasty triggers within relocate_kernel that would
necessitate a working debug mechanism ...
Also, printing something to the early console using these new
relocate_kernel printing functions would be an additional bonus as
well, for similar reasons.
Thanks,
