Merge tag 'perf-core-for-mingo-20160323' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/core improvements and fixes:

User visible fixes:

 - Fix documentation of :ppp modifier in 'perf list' (Andi Kleen)

 - Fix silly nodes bitfield bits/bytes length assertion in 'perf bench numa' (Jakub Jelen)

 - Remove redundant CPU output in libtraceevent (Steven Rostedt)

 - Remove 'core_id' check in topology 'perf test' (Sukadev Bhattiprolu)

Infrastructure changes/fixes:

 - Record text offset in dso to calculate objdump address, to use with
   modules in addition to vDSO symbol address calculations (Wang Nan)

 - Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo)

 - Add cpumode to the perf_sample struct, this way we don't need to pass
   the union event to the machine and thread resolving routines, shortening
   function signatures and allowing the future introduction of a way
   to use tracepoint events instead of the unavailable HW cycles counter on
   powerpc guests in perf kvm by just hooking on perf_evsel__parse_sample,
   at the end (Arnaldo Carvalho de Melo)

 - Remove/unexport die() related infrastructure, that at some point will
   finally be removed (Arnaldo Carvalho de Melo)

 - Adopt linux/stringify.h from the kernel sources, not to touch this
   kernel header from tools/ (Arnaldo Carvalho de Melo)

 - Stop using strbuf for things we can instead trivially use libc's asprintf()
   (Arnaldo Carvalho de Melo)

 - Ditch tools/lib/util/abspath.c, its only exported function was used at just
   one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo)

 - Use strerror_r() in the llvm infrastructure, tread safe, its what is used
   elsewhere in tools/perf/ (Arnaldo Carvalho de Melo)

Cleanups:

 - Removed misplaced or needless __maybe_unused/export (Arnaldo Carvalho de Melo)
