Trying to apply the patchkit:
[acme@zoo linux]$ make -C tools clean > /dev/null 2>&1 [acme@zoo linux]$ make -C tools/perf build-test make: Entering directory '/home/git/linux/tools/perf' Testing Makefile tests/make:15: /scripts/Makefile.arch: No such file or directory make[2]: *** No rule to make target '/scripts/Makefile.arch'. Stop. tests/make:5: recipe for target 'all' failed make[1]: *** [all] Error 2 Makefile:81: recipe for target 'build-test' failed make: *** [build-test] Error 2 make: Leaving directory '/home/git/linux/tools/perf' [acme@zoo linux]$
