--------------------------------

[ Upstream commit 3584c1db ]

These particular errors can be encountered while trying to kexec when
secureboot lockdown is in place.  Without this change, even with a
signed debug build, one still needs to reboot the machine to add the
appropriate dyndbg parameters (since lockdown blocks debugfs).

Accordingly, upgrade all pr_debug() before fatal error into pr_warn().
