The measurement list is dumped during a soft reset (kexec) through the call
to print_hex_dump(KERN_DEBUG, ...), printing to the system log ignoring both
DEBUG build flag and CONFIG_DYNAMIC_DEBUG option.
To honor the above conditions the macro print_hex_dump_debug() should be
used instead, thus depending on the enabled option/flag the output is given
by a different function call or even silenced.
