Subject: kexec: print out debugging message if required for kexec_load
Date: Wed, 26 Nov 2025 16:44:27 +0800

commit a85ee18c7900 ("kexec_file: print out debugging message if
required") has added general code printing in kexec_file_load(), but not
in kexec_load().

As a result, when using '-d' for the kexec_load interface, print nothing
in the kernel space.

And print out type/start/head of kimage and flags to help debug.
