| 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. |
