From: Sahara <keun-o.p...@darkmatter.ae> This series of patches introduce the arm64 arch_within_stack_frames implementation using stacktrace functions. Also the base code is moved from thread_info.h to stacktrace.h. x86 code is reimplemented to use frame pointer unwinder functions.
Note: The code is still missing in case of using x86 ORC unwinder and guess unwinder. v2 changes: - Remove 'arm64: usercopy: consider dynamic array stack variable' - minor fix in x86 arch_within_stack_frames code.
