That's a gcc builtin function, not a kernel function.

If you pass the address you get to addr2line, you should find the
function name, etc.  Here's the documentation for addr2line:
    http://sources.redhat.com/binutils/docs-2.12/binutils.info/addr2line.html#addr2line

If you want to get that information from within the program, without
using an external program, then you are going to have to link your
program against libbfd and call bfd_find_nearest_line().  Look at the
sources to addr2line for some hints.
