Subject: [PATCH v3 0/3] usercopy: reimplement arch_within_stack_frames
Date:   Mon,  9 Apr 2018 15:59:13 +0400
Message-Id: <1523275156-29087-1-git-send-email-kpark3469@gmail.com>

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

  x86: usercopy: reimplement arch_within_stack_frames with unwinder
