2015-11-07kexec: use file name as the output message prefixMinfei Huang
kexec output message misses the prefix "kexec", when Dave Young split the kexec code. Now, we use file name as the output message prefix. Currently, 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.

2015-09-10kexec: split kexec_file syscall code to kexec_file.cDave Young
Split kexec_file syscall related code to another file kernel/kexec_file.c so that the #ifdef CONFIG_KEXEC_FILE in kexec.c can be dropped. Sharing variables and functions are moved to kernel/kexec_internal.h per suggestion from Vivek and Petr.
