Description

This PR adds some of the newer m68k linux syscalls.

Unsure why I have merge conflicts since the diff looks clean on the files changed tab.

It looks like this is based on 600e1d1, which was from about a year ago. This file doesn't get touched much, but there are a handful of changes since then.
