These are the first two common patches in my series to introduce sparsemem support to RISC-V. 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 add the new feature to riscv. I would suggest we merge these two patches through Andrew's mm tree.
