As far as most archs are concerned, golang.org/x/sys v0.1.0 and up use libc functions instead of syscall() for its own use, so the biggest problem for x/sys is with older 'dated' v0.0.0-202xxxxx (iirc this changed in 202208something for most archs, but not until December for mips64). However x/sys/unix also has tables listing syscall numbers which is outdated even in git head. Some other modules use these tables with syscall() and still run into problems (in particular noticed with modernc.org/sqlite). mmap is the biggest problem - just updating the numbers in x/sys/unix isn't enough though; the parameters changed too. Search ports@ archives for gotosocial for more info.
