I think the main one is fixing the dynamic SCS patching when full LTO is enabled (clang was silently getting this horribly wrong), but it's all good stuff. Rob just pointed out that the fix to the workaround for erratum #2966298 might not be necessary, but in the worst case it's harmless and since the official description leaves a little to be desired here, I've left it in.
