commit432746f8e0upstream. When we call symbol__fixup_duplicate() we use algorithms to pick the "best" symbols for cases where there are various functions/aliases to an address, and those check zero size symbols, which, before calling symbol__fixup_end() are _all_ symbols in a just parsed kallsyms file. So first fixup the end, then fixup the duplicates. Found while trying to figure out why 'perf test vmlinux' failed, see the output of 'perf test -v vmlinux' to see cases where the symbols picked as best for vmlinux don't match the ones picked for kallsyms.
