The internal kallsyms tables contain information which could be quite
useful to a debugging tool in the absence of other debuginfo. If
kallsyms is enabled, then a debugging tool could parse it and use it as
a fallback symbol table. Combined with BTF data, live & post-mortem
debuggers can support
To include kallsyms data in the vmcoreinfo note, we must make the symbol
declarations visible outside of kallsyms.c. Move these to a new internal
header file.

The kernel can be configured to contain a lot of introspection or
debugging information built-in, such as ORC for unwinding stack traces,
BTF for type information, and of course kallsyms. Debuggers could use
this information to navigate a core dump or live system, but they need
to be able to find
