Subject: [PATCH v4 7/7] kexec_file, parisc: print out debugging message if required
Date:   Wed, 13 Dec 2023 13:57:47 +0800

Then when specifying '-d' for kexec_file_load interface, loaded
locations of kernel/initrd/cmdline etc can be printed out to help
debug.

Here replace pr_debug() with the newly added kexec_dprintk() in
kexec_file loading related codes.
