Only "pymod -S path/to/debuginfo" works.

x86_64: fix active task %rip retrieval, clear up scheduled task's
registers retrieval.
Currently it serves only for finding & loading debuginfo. It should be
invoked like "mod -S path/to/module/debuginfos". It searches for all the
*.ko.debug files under the given path, then walks the list of loaded
modules and is trying to load the debuginfo at the given address.

Shouldn't the debuginfos be located via the notes in the module .ko files?

Yeah ... AFAIK those notes may not always exist. But that could be added later if someone needs debugging a kernel compiled without the notes.

This is my initial version, which entirely ignores all the .ko files. Because at first I was using dumps from SLE11 where all we needed was the debuginfo. Yes, the logic should be better (and ideally preventing you from loading nonmatching files).
