While adding support for kexec, Nick recently copied the arm64 copy_oldmem_page() into the RISC-V port. Since this is shared verbatim with arm and arm64 already, I'd like to add a generic version and so we can use it instead. I haven't converted over the MIPS, PPC, or SH ports: while I think we could figure out how to share a version, they're not exactly the same right now. S/390 and x86 are definitely meaningfully different.
Unless there are any objections I'll include the first patch along with the RISC-V kexec support, which I'm hoping to have for 5.9. The code, based on 5.8-rc4, is at ssh://git@gitolite.kernel.org/pub/scm/linux/kernel/git/palmer/linux.git -b copy_oldmem_page .
