6.1-stable review patch. If anyone has any objections, please let me know.

From: Jiri Olsa jolsa@kernel.org
commit 73feb8d5fa3b755bb51077c0aabfb6aa556fd498 upstream.
Making module_kallsyms_on_each_symbol generally available, so it can be used outside CONFIG_LIVEPATCH option in following changes.
Rather than adding another ifdef option let's make the function generally available (when CONFIG_KALLSYMS and CONFIG_MODULES options are defined).
