The patches are independent of each other and apply on mm-nonmm-unstable. Since the original posting: - "selftests/prctl: build generated tests for the target architecture" is dropped. "selftests/prctl: select the tests by ARCH alone" in mm-nonmm-unstable replaces it. - "selftests/thermal: allow cross builds of the Intel tests" is dropped, it went in through the thermal tree as ff4194e54f84. - The size patch has Thomas's Reviewed-by.
