Subject: [PATCH 0/4] usercopy: reimplement arch_within_stack_frames
From: Sahara <keun-o.park@...kmatter.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.
James Morse (1):
arm64: usercopy: implement arch_within_stack_frames
Sahara (3):
stacktrace: move arch_within_stack_frames from thread_info.h
arm64: usercopy: consider dynamic array stack variable
x86: usercopy: reimplement arch_within_stack_frames with unwinder
