Mark Rutland f89f20acff Documentation: livepatch: document reliable stacktrace ... Add documentation for reliable stacktrace. This is intended to describe the semantics and to be an aid for implementing architecture support for HAVE_RELIABLE_STACKTRACE. Unwinding is a subtle area, and architectures vary greatly in both implementation and the set of concerns that affect them, so I've tried to avoid making this too specific to any given architecture. I've used examples from both x86_64 and arm64 to explain corner cases in more detail, but I've tried to keep the descriptions sufficient for those who are unfamiliar with the particular architecture. This document aims to give rationale for all the recommendations and requirements, since that makes it easier to spot nearby issues, or when a check happens to catch a few things at once.
