Thanks for posting it again. I tried to read through it and point out a few things I noticed. It's been a while since v2, so I may have forgotten things we already discussed. I did not see any major issues here, the main things that take work to implement (better atomics, vmemmap, also vmap_stack which I did not mention) are just there to make your code better, but are not required to get it merged. > This is an RFC, since kvx support is not yet upstreamed into gcc, > therefore this patch series cannot be merged into Linux for now. Do you have a timeline for upstream compiler support? I see that your github trees contain both llvm and gcc forks on an older baseline (gcc-12.2 and llvm-15, respectively), but I don't know how much you have already submitting for inclusion in a newer release.
