kexec output message misses the prefix "kexec", when Dave Young split the kexec code. Now, we use file name as the output message prefix.
Currectly, the format of output message: [ 140.290795] SYSC_kexec_load: hello, world [ 140.291534] kexec: sanity_check_segment_list: hello, world Ideally, the format of output message: [ 30.791503] kexec: SYSC_kexec_load, Hello, world [ 79.182752] kexec_core: sanity_check_segment_list, Hello, world Remove the custom prefix "kexec" in output message.
