New features: - Add 'brstackinsn' field in 'perf script' to reuse the x86 instruction decoder used in the Intel PT code to study hot paths to samples (Andi Kleen) Kernel: - Default UPROBES_EVENTS to Y (Alexei Starovoitov) - Fix check for kretprobe offset within function entry (Naveen N. Rao) Infrastructure: - Introduce util func is_sdt_event() (Ravi Bangoria) - Make perf_event__synthesize_mmap_events() scale on older kernels where reading /proc/pid/maps is way slower than reading /proc/pid/task/pid/maps (Stephane Eranian) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJYyrdSAAoJENZQFvNTUqpAe+4P/3c4ilBSOxLCCxGO7jDYo9oq /KqlvsCIg7+vo5eqrOUJAb4qXFnvpYxwjMMkL5rx7gdsBCRfRXIINGWUMrq5mNyk MgxuqYnp+yRuxLYml2wn+tdwLzcHWSN2EO9mqQ14N4I+HvgdLmVPQ44ACQXs6KfL dk/Ix8YtnFWl2sDZjvyr7ZBqwCPzzklZgHM6erxNUr/WJspzUiixAWqUmewodOUl P3PitlHXkITOK3AxSqOjJ4g1k933215nGih7hr0XdjEm4pIYaYksShQ6k9DASCrv dn2o1pF1LTu7KCtAo70aaSB7GXydwoA//o2gRbDkSwJJ25DIImZxJXQz9PAYDOo1 vXSIhmlQ72c4/Yv/XzVOrIoMMMpmWKS3lGZxMVGR/Ie9Gw4kbotkaoEqEpNQsaDZ iIaU5v/EcvvToT7T7VHrGg0+vmHgYxm5gSlyASi2IrO2/wJAs0v2pYfuL6gYhXGp mhv/pHUv4l9OW+Ubm+zJEEcg337c2RQU5wT/bk4PihxY6nQyEH2Pn5VzdNbZLuMR eWnqTH/md+8/bkhmuZJp71wm60oPHoPvbDjvtfVmXAa52AzO+NWSc9Veke3C/QRm XgNkrXlzeKopEso3j4gw2iAolqw9t8FHFLGgbTkS+6UCKjAM7vNLiIV02LQqhM50 qCnKEusMDCRgzeOXxYt+ =Bg5M -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.12-20170316' 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: New features: - Add 'brstackinsn' field in 'perf script' to reuse the x86 instruction decoder used in the Intel PT code to study hot paths to samples (Andi Kleen) Kernel changes: - Default UPROBES_EVENTS to Y (Alexei Starovoitov) - Fix check for kretprobe offset within function entry (Naveen N.
