The 'perf' Makefile is flaky on some kernel versions. It will still parallelize the build even with 'make -j1' because it explicitly invokes a sub-make with the correct flags. But the top-level make is not smart enough to handle large '-j' values. Signed-off-by: Steven Noonan <steven@uplinklabs.net> --- package/perf/perf.mk | 2 ++ 1 file changed, 2 insertions(+)
