Hi Linus and maintainers,
below is a series to switch mips, sh and sparc64 to use the generic GUP code so that we only have one codebase to touch for further improvements to this code. I don't have hardware for any of these architectures, and generally no clue about their page table management, so handle with care.
Changes since v1: - fix various issues found by the build bot - cherry pick and use the untagged_addr helper form Andrey - add various refactoring patches to share more code over architectures - move the powerpc hugepd code to mm/gup.c and sync it with the generic hup semantics
