[PATCH v2 0/5] bsd-user: Generate system call numbers
Posted by Warner Losh 10 hours ago
FreeBSD has a system call number header, sys/syscall.h, that's installed
on every system that can compile qemu. Generate the system call numbers
from that table rather than re-regenerating it yet again.

To do this, I have to clean up a few stragglers for system calls we've
removed. But these returned not supported anyway, so there's no net
change.

I also tried to do this in a way that the other bsds can coexist with
should they show up again in the future. To that end, I moved the
definition of time_t into os-syscall.h, where I noticed it was wrong for
amd64 targets (which is little used and missing features, so it went
unnoticed for a long time).

More will be generated in the future, but this is the first steps.

Finally, while this does add files, no adjustment to MAINTAINERS is
needed.
