It's sufficient now, but there might be a need in the future.
Also, there's kexec_dprintk. Judging from its name, it seems like a 
universal kexec print.
Looking at the code, it feels like not only the kexec_file interface 
path uses it for printing.

So, would it be better to rename kexec_file_dbg_print to kexec_dbg_print.
