Subject: [PATCH v2 0/3] usercopy: reimplement arch_within_stack_frames
Date:   Mon,  9 Apr 2018 10:06:06 +0400

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.

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
