kallsyms: expand symbol name into comment for debugging
The assembler output of kallsyms.c is not meant for people to understand, and is generally not helpful when debugging "Inconsistent kallsyms data" warnings. I have previously struggled with these, but found it helpful to list which symbols changed between the first and second pass in the .tmp_vmlinux.kallsyms*.S files. As this file is preprocessed, it's possible to add a C-style multiline comment with the full type/name tuple.
