Merge tag 'perf-core-for-mingo' of... 

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

 into perf/core

perf/core improvements and fixes:

 * Reset SIGTERM handler in workload child process, fix from David Ahern.

 * Handle death by SIGTERM in 'perf record', fix from David Ahern.

 * Fix printing of perf_event_paranoid message, from David Ahern.

 * Handle realloc failures in 'perf kvm', from David Ahern.

 * Fix divide by 0 in variance, from David Ahern.

 * Save parent pid in thread struct, from David Ahern.

 * Handle JITed code in shared memory, from Andi Kleen.

 * Makefile reorganization, prep work for Kconfig patches, from Jiri Olsa.

 * Fixes for 'perf diff', from Jiri Olsa.

 * Add automated make test suite, from Jiri Olsa.

 * 'perf tests' fixes from Jiri Olsa.

 * Remove some unused struct members, from Jiri Olsa.

 * Add missing liblk.a dependency for python/perf.so, fix from Jiri Olsa.

 * Respect CROSS_COMPILE in liblk.a, from Rabin Vincent.

 * Expand definition of sysfs format attribute, from Michael Ellerman.

 * No need to do locking when adding hists in perf report, only 'top'
   needs that, from Namhyung Kim.

 * Sorting improvements, from Namhyung Kim.

 * Fix alignment of symbol column in in the hists browser (top, report)
   when -v is given, from NAmhyung Kim.

 * Add --percent-limit option to 'top' and 'report', from Namhyung Kim.

 * Fix 'perf top' -E option behavior, from Namhyung Kim.

 * Fix bug in isupper() and islower(), from Sukadev Bhattiprolu.
