[PATCH 0/9] perf build: Make build-test faster

[Wang Nan]

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
