From: Jiri Olsa Date: Sun, 1 Mar 2015 20:19:44 +0000 (+0100) Subject: perf build: Move feature checks code under tools/build X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e6c76d620379fd65fc0310aee1785ff7b1b10236;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf build: Move feature checks code under tools/build Moving feature checks code under tools/build directory. Changing also $feature_dir to point to new feature directory location and perf Makefiles to include Makefile.feature from new location.
