[RFC v4 0/9] Support for Linux kernel debugging

Hi everybody,

here is finally v4 of my patch set.

Despite the announcement made with v3, I turned away from the idea to only
add patches on top. While the idea sounds good reality showed that
resolving all merge conflicts and splitting them up so they can easily be
squashed into the original commits is not that nice.

New in v4:
* Rebase to current master (fd0219988d).
* Add S390 kernel stack unwinder (requires new patch #8).
* C++-ify module support.
* Rewrite module relocation to mimic kernel better.
* Adapt to new ptid_t API.
* Update commit messages.
* Fix some typos and coding style violations.
