Upstream the file, thread, socket and remaining signal system calls (too numerous to list here).
This series is an ambitous use of claude to help me upstream all the remaining system calls. I've batched them together in what I think are reasonable chunks, and had claude do the grunt work of copying the code over and attributing the commits from our complex branching history. The chopping up was a bit arbitrary, but I think it's good. The commit messages may be a little weak, but may also be OK. I've also double checked the style and made fixes upstream for them as well. Claude also reviewed all these changes and found a few bugs that I've fixed. I've personally read through them all and haven't found anything glaring. I fixed all the bugs that were found, in most cases differently than claude's suggestions. I've added 'Assisted-by: Claude...' to all these commits to reflect my leaning on Claude so hard. This use falls within the 'non-creative' use that the Qemu project has said is OK. If that's not the right thing to do, I can remove them. This leaves sysctl translation, the powerpc architecture support, coredumps and a transition to 'truss' based system call tracing. With these changes applied we'er down from a high of about 30k lines of diffs to only 5k (not counting genereted, but checked in files in blitz). The changes are 8k, so maybe a bit ambitious from that perspective as well. There's a few lines over 80 that I've not cleaned up. Let me know if that's a problem. The other warnings are about adding files, and there's no new MAINTAINERS entry needed. And the 'arch dependent defines should be avoided' are needed to cope with different FreeBSD build systems having different system calls. Finally, a number of bugs were found late in the process, and not all were squashed back since the patch series is a bit unwieldy, and it helps me to make sure I've applied the fixes found during review to blitz. I know this pushes us past the suggested 50 chunks, but I felt it important to keep them seprate since Claude identified all the issues. I think it's important to have another set of eyes on the changes that I made to fix them. I'd be open to feedback other ways to handle this. This is a big experiment, in many ways, for me, so I'm interested in whatever feedback you may have to make things better in the future.
