Merge tag 'perf-core-for-mingo-4.11-20170213' 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:
- Introduce the 'delta-abs' 'perf diff' compute method, that orders the
histogram entries by the absolute value of the percentage delta for a
function in two perf.data files, i.e. the functions that changed the
most (increase or decrease in samples) comes first (Namhyung Kim)
User visible changes:
- Improve message about tweaking the kernel.perf_event_paranoid setting,
telling how to make the change permanent by editing /etc/sysctl.conf
(Arnaldo Carvalho de Melo)
Infrastructure changes:
- Introduce linux/compiler-gcc.h as a counterpart to the kernel's,
initially containing the definition of __fallthrough, more to
come (__maybe_unused, etc) (Arnaldo Carvalho de Melo)
- Fixes for problems uncovered by building tools/perf with clang, such
as always true tests of arrays against NULL and variables that sometimes
were used without being initialized (Arnaldo Carvalho de Melo, Steven Rostedt)
- Before loading a new ELF, clear global variables set by the
samples/bpf loader (Mickaël Salaün)
- Ignore already processed ELF sections in the samples/bpf
loader (Mickaël Salaün)
- Fix compile error in the scripting code with some perl5
versions (Wang YanQing)
