[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo <acme@kernel.org>]

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...

  perf script: Add support for printing assembler (2016-03-29 20:15:16 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Add support for printing assembler using the udis86 library (Andi Kleen)

  E.g.:

  # perf record -e intel_pt// true
  # perf script -F ip,sym,asm

  ffffffff8119e069 event_sched_in.isra.93
 	call 0x81c29600
  <SNIP>

- 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)
