Merge tag 'perf-urgent-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
. perf probe: Fix segfault due to testing the wrong pointer for NULL,
from Ananth N Mavinakayanahalli.
. libtraceevent: Remove hard coded include to /usr/local/include in
Makefile, which causes cross builds to include host header files,
fix from Jack Mitchell.
. perf record: Use the right target interface for synthesizing
threads when --cpu/-C option is used, fix from Jiri Olsa.
. Check if -DFORTIFY_SOURCE=2 is allowed, as gcc 4.7.2 defines
it and then the build is broken when it is redefined in perf,
fix from Marcin Slusarz.
. Fix build with NO_NEWT=1, that can happen explicitely or when
the newt-devel package is not installed, from Michael Ellerman.
. perf/POWER7: Create a sysfs format entry for Power7 events, missing
patch from a patchseries already merged, from Sukadev Bhattiprolu.
. Fix LIBNUMA build with glibc 2.12 and older, from Vinson Lee.
