Description

I don't remember exactly what gnustep uses libkvm for. I think it's something fairly trivial, like getting the arguments to the running process. We used to use /proc, but since the change to not mounting /proc by default we had to revert to this. glibc provides a global variable that contains a copy of argv, which might be a sensible thing to consider adding. https://github.com/seanbruno/qemu-bsd-user/commit/f160a709984182f673a1887d37916b45a0d2a05f should fix this problem. The kinfo_proc structure was not being properly sized and byte swapped by the sysctl() system handler. The conversion is a bit messy given that kinfo_proc is a rather large and somewhat ugly structure. The kinfo warning is now gone. However, the build crashes qemu-arm:
