Subject: selftests/powerpc: Use the test harness for the TM DSCR test
X-Git-Tag: v4.14-rc1~7163^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aa83f3d8979528d2e6e8ad0c155d8ecf4eaef2e2;p=platform%2Fkernel%2Flinux-rpi.git

selftests/powerpc: Use the test harness for the TM DSCR test

This gives us standardised success/failure output and also handles
killing the test if it runs forever (2 minutes).
