v2: - rebase on latest tip - remove NULL task pointer convention ---
The last version was posted as part of a much larger patch set: https://lkml.kernel.org/r/cover.1471525031.git.jpoim...@redhat.com People complained about the set being too big, so it was split up into more digestible pieces. All the prerequisite patches for the unwinder have now been merged. See patch 1/6 for the background and justification for this change. Josh Poimboeuf (6): x86/unwind: add new unwind interface and implementations perf/x86: convert perf_callchain_kernel() to use the new unwinder x86/stacktrace: convert save_stack_trace_*() to use the new unwinder oprofile/x86: convert x86_backtrace() to use the new unwinder x86/dumpstack: convert show_trace_log_lvl() to use the new unwinder x86/dumpstack: remove dump_trace() and related callbacks arch/x86/events/core.c | 33 +++----- arch/x86/include/asm/stacktrace.h | 46 +---------- arch/x86/include/asm/unwind.h | 73 ++++++++++++++++ arch/x86/kernel/Makefile | 6 ++ arch/x86/kernel/dumpstack.c | 170 +++++++++++++++++--------------------- arch/x86/kernel/dumpstack_32.c | 44 +--------- arch/x86/kernel/dumpstack_64.c | 78 +---------------- arch/x86/kernel/stacktrace.c | 74 +++++++---------- arch/x86/kernel/unwind_frame.c | 93 +++++++++++++++++++++ arch/x86/kernel/unwind_guess.c | 43 ++++++++++ arch/x86/oprofile/backtrace.c | 39 ++++----- 11 files changed, 357 insertions(+), 342 deletions(-) create mode 100644 arch/x86/include/asm/unwind.h create mode 100644 arch/x86/kernel/unwind_frame.c create mode 100644 arch/x86/kernel/unwind_guess.c -- 2.7.4
