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 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 arch/arm64/Kconfig | 1 + arch/arm64/kernel/stacktrace.c | 76 +++++++++++++++++++++++++++++++++ arch/x86/include/asm/thread_info.h | 51 +--------------------- arch/x86/include/asm/unwind.h | 5 +++ arch/x86/kernel/Makefile | 2 +- arch/x86/kernel/stacktrace.c | 87 ++++++++++++++++++++++++++++++++++++++ arch/x86/kernel/unwind_frame.c | 4 +- include/linux/page_ext.h | 1 - include/linux/stacktrace.h | 24 +++++++++++ include/linux/thread_info.h | 21 --------- mm/usercopy.c | 2 +- 11 files changed, 197 insertions(+), 77 deletions(-) -- 2.7.4
