Subject: 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.
