Subject: [GIT PULL 00/11] perf/core improvements and fixes
Hi Ingo,
Please consider pulling, this is on top of my previously submitted
acme/perf/urgent, so that we can test Andi's udis86 work on 'perf script'.
This is now test built in several more docker images, including
minimal feature cross-compiler builds ones:
# dm
minimal-debian-experimental-x-mips64: Ok
minimal-debian-experimental-x-mips64el: Ok
minimal-debian-experimental-x-mipsel: Ok
minimal-ubuntu-x-arm: Ok
minimal-ubuntu-x-arm64: Ok
minimal-ubuntu-x-ppc64: Ok
minimal-ubuntu-x-ppc64el: Ok
alldeps-debian: Ok
alldeps-mageia: Ok
alldeps-rhel7: Ok
alldeps-centos: Ok
alldeps-opensuse: Ok
alldeps-ubuntu: Ok
#
Those x-arch cross docker images already allow me to avoid introducing
bugs like the powerpc one Sukadev spotted.
I need to figure out how to install more devel packages for things like
libelf-devel:arch in debian/ubuntu, I almost got there with 'dpkg
--add-architecture arch', but I still need to figure out how to find the list
of multilib enabled devel packages to allow me to have devel packages for other
arches than the native one...

- Add support for skipping itrace instructions, useful to fast forward
processor trace (Intel PT, BTS) to right after initialization code at the start
of a workload (Andi Kleen)
- Add support for backtraces in perl 'perf script's (Dima Kogan)
- Add -U/-K (--all-user/--all-kernel) options to 'perf mem' (Jiri Olsa)
- Make -f/--force option documentation consistent across tools (Jiri Olsa)
Infrastructure:
- Add 'perf test' to check for event times (Jiri Olsa)
- 'perf config' cleanups (Taeung Song)
