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> -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJXVyVuAAoJENZQFvNTUqpAcXAP/R+mXODq3brY9C9N4/ujnAvc vu/WHq7J1kbL8JrAsUHos0avPCZJigibx3rzG6ZuV3SqOpvKBc7hy+nSOrRyXgT3 QG8mMpdhgyexCYRkd8nELAxS2q1E6XzeHJ5Ot5gcHx+N1QCCTm9xZ4++m5ee/Juo 0ceud29dljmjjTehAzEht5N4fgRPavAwjO8DTYVQF0+hMPbGQE7EAS7LF+mDTFxY UAe7n1buyBm4Y/OLXNP79zQG78eSktau3amUiZ/W3owJkhbUrE7trfWNnNPCYQVU ySVm0xbmy8fdhm6XNxCem+ya9SZ1ROF71A0FiDWlShioutcKBbustBo5UO82Rjxg htHLOoE08BqniIWrqg8VCG2SP8PjzC9JrjxsppnZd4UgfgvwJ0hmRZ++h5dN1HFk /RK2GJTot4EaxR9etkWG9R1sCBLAtJy+MLO/oHMxpR8Rw/1RlJRPV7amnLMvrmdx wRlEVa+OkV0Yb968aai9DObqOkNmNSMLXXQ5ez5T01h2+VjA/PV7UtJ7z0O7Nk4L lyn6e1IE5uko1oaPJqNhfnu7imq1AhRt8ysXfEHF4RD+eIlUMTZNxRzfyruKyJXo YUxpfVGho60pYKMYHjriH966wWxCmWZhhY2qERbt3A9ECkVuagUWiFwx/u5ngiG1 BWxVkGtBh1yUKuttY7We =DvZE -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-20160607' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - 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.
