Hi, Jiri and Arnaldo,

You can find this series on git-tree:

git://git.kernel.org/pub/scm/linux/kernel/git/pi3orama/linux.git perf/build-test

Other patches I sent these days can be found in perf/ebpf and perf/overwrite.

Thank you.

Utilize Jiri's two RFCs to make build-test faster.

Before his RFC on a 24 core machine:
real 21m16.579s
user 176m12.989s
sys 20m54.950s

After his RFC:
real 16m0.619s
user 172m53.896s
sys 19m22.777s

Speedup: 24.75%.

Jiri Olsa (2):
perf build: Add feature-dump target
perf build: Introduce FEATURES_DUMP make variable

Wang Nan (7):
perf build: Set parallel making options build-test
perf build: Pass O option to Makefile.perf in build-test
perf build: Test correct path of perf in build-test
perf build: Pass O option to kernel makefile in build-test
tools build: Allow subprojects select all feature checkers
perf build: Select all feature checkers for feature-dump
perf build: Use feature dump file for build-test
