Hi Ingo,
Please consider pulling, this is on top of perf-core-for-mingo-20160606,
Thanks,

The following changes since commit 7db91f251056f90fec4121f028680ab3153a0f3c:

perf callchain: Support aarch64 cross-platform (2016-06-07 15:13:35 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Support cross unwinding, i.e. collecting '--call-graph dwarf' perf.data files
in one machine and then doing analysis in another machine of a different
hardware architecture. This enables, for instance, to do:
perf record -a --call-graph dwarf
on a x86-32 or aarch64 system and then do 'perf report' on it on a
x86_64 workstation. (He Kuang)
- Fix crash in build_id_cache__kallsyms_path(), recent regression (Wang Nan)
Infrastructure:
- Make tools/lib/bpf use the IS_ERR return facility consistently and also stop
using the _get_ term for non-reference count methods (Arnaldo Carvalho de Melo)
- 'perf config' refactorings (Taeung Song)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (7):
tools lib bpf: Use IS_ERR() reporting macros with bpf_map__get_private()
tools lib bpf: Rename bpf_map__get_name() to bpf_map__name()
tools lib bpf: Use IS_ERR() reporting macros with bpf_map__get_def()
tools lib bpf: Rename bpf_map__get_fd() to bpf_map__fd()
tools lib bpf: Remove _get_ from non-refcount method names
tools lib bpf: Make bpf_program__get_private() use IS_ERR()
tools lib bpf: Rename set_private() to set_priv()
He Kuang (14):
perf unwind: Use LIBUNWIND_DIR for remote libunwind feature check
perf unwind: Decouple thread->address_space on libunwind
perf unwind: Introduce 'struct unwind_libunwind_ops' for local unwind
perf unwind: Move unwind__prepare_access from thread_new into thread__insert_map
perf unwind: Don't mix LIBUNWIND_LIBS into LIBUNWIND_LDFLAGS
perf unwind: Separate local/remote libunwind config
perf unwind: Rename unwind-libunwind.c to unwind-libunwind-local.c

perf unwind: Check the target platform before assigning unwind methods
perf unwind: Change fixed name of libunwind__arch_reg_id to macro
perf unwind: Introduce flag to separate local/remote unwind compilation
perf callchain: Support x86 target platform
perf callchain: Support aarch64 cross-platform
Taeung Song (2):
perf config: Constructor should free its allocated memory when failing

Wang Nan (1):
perf tools: Fix crash in build_id_cache__kallsyms_path()
