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/[email protected] 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
