Subject: [PATCH v4 02/21] kallsyms: Export kallsyms_lookup_name

Module like minidump providing debugging support will need to
get the symbol information from the core kernel e.g to get
the linux_banner, kernel section addresses bss, data, ro etc.

commit 0bd476e6c671 ("kallsyms: unexport kallsyms_lookup_name()
 and kallsyms_on_each_symbol()") unexports kallsyms_lookup_name
due to lack of in-tree user of the symbol. Now, that minidump
will one of its user, export it.
