I am working on patch series to add an install target to the main kernel makefile, so these tests can be built and installed on a target just like we do with kernel and modules. I hope to get this in 3.19 or definitely into 3.20 This probably will help address the problem you are seeing. Install target is needed for qemu type environments as well. thanks, -- Shuah -- Shuah Khan Sr. Linux Kernel Developer Samsung Research America (Silicon Valley) shuahkh@osg.samsung.com | (970) 217-8978
