I put the snapshot of the WIP of the merge to 11.1 at https://kib.kiev.ua/kib/amd64_11.1_meltdown.1.patch I only compiled this on the stable/11, not even booted. I suspect that it is not compilable on 11.1 because apparently the patch depends on some features of assembler only added in clang 5.0. If somebody does the runtime test of the patch, it would be useful.
