From: Arnd Bergmann <arnd****@arndb*****> I had run into some regressions for the previous version of this series, the new version is based on v5.14-rc2 instead. These two functions appear to be unnecessarily different between architectures, and the asm-generic version is a bit questionable, even for NOMMU architectures. Clean this up to just use the generic library version for anything that uses the generic version today. I've expanded on the patch descriptions a little, as suggested by Christoph Hellwig, but I suspect a more detailed review would uncover additional problems with the custom versions that are getting removed. I ended up adding patches for csky and microblaze as they had the same implementation that I removed elsewhere, these are now gone as well. If I hear no objections from architecture maintainers or new build regressions, I'll queue these up in the asm-generic tree for 5.15.
