Subject: [GIT PULL 00/19] perf/core improvements and fixes
Hi Ingo,
Please consider pulling,
I've added building objtool to most of the containers in my build test setup:

perf test: Add a test case for SDT event (2016-07-13 23:09:10 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Finish merging initial SDT (Statically Defined Traces) support, see
cset comments for details about how it all works (Masami Hiramatsu)
- Support attaching eBPF programs to tracepoints (Wang Nan)
Infrastructure:
- Fix up BITS_PER_LONG setting (Arnaldo Carvalho de Melo)
- Add fallback from ELF_C_READ_MMAP to ELF_C_READ in objtool, fixing
the build in libelf implementations lacking that elf_begin() cmd,
such as Alpine Linux's (Arnaldo Carvalho de Melo)
- Avoid checking code drift on busybox's diff in objtool (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (3):
tools: Fix up BITS_PER_LONG setting
objtool: Add fallback from ELF_C_READ_MMAP to ELF_C_READ
objtool: Avoid checking code drift on busybox's diff
Masami Hiramatsu (11):
perf probe: Fix to show correct error message for $vars and $params
perf probe: Accept %sdt and %cached event name
perf probe: Make --list show only available cached events
perf probe-cache: Add for_each_probe_cache_entry() wrapper

perf probe: Support @BUILDID or @FILE suffix for SDT events
perf probe: Support a special SDT probe format
perf build: Add sdt feature detection
perf test: Add a test case for SDT event
Wang Nan (5):
tools lib bpf: New API to adjust type of a BPF program
tools lib bpf: Report error when kernel doesn't support program type
perf event parser: Add const qualifier to evt_name and sys_name
perf bpf: Rename bpf__foreach_tev() to bpf__foreach_event()
