From: Sahara <keun-o.park@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. v3 changes: - Fix build problem caused by circular inclusion of header in x86 UP config v4 changes: - Fix build problem caused by page_ext.h change
James Morse (1): arm64: usercopy: implement arch_within_stack_frames
Sahara (2): stacktrace: move arch_within_stack_frames from thread_info.h x86: usercopy: reimplement arch_within_stack_frames with unwinder
