The full series was posted last cycle here [1] and the latest version can be found here [2]. As recommended by Palmer, I'd like to get the changes to common code merged and then I will pursue the cleanups in the individual arches (arm, arm64, and sh) as well as adding the new feature to riscv. I would suggest we merge these two patches through Andrew's mm tree.
