soutade_gmail.com added a comment to D7970: Linux ARM v2 1/9.

This patchset has been created for FreeBSD 11. It has not been tested nor maintened since and I currently don't have time to work on it. I think we can drop it (it can be a base for new contributors).

There are also a few syscalls that were removed when they changed to EABI. I don't see a need for us to support the syscalls userspace will never call.

Gregory,
I take it v2 reviews are the ones that are relevant and that should be reviewed/tested. And previous 16 reviews can be closed now? Is that right?
Thank you

Right. They're strictly the same (except an update needed to compile in new HEAD) but the first version is more Linux like patchset while the second is FreeBSD style.

Gregory,
Could you close all Linux-style revisions? Go to the bottom of the page and choose "Abandon" action with comment like "Overtaken by D7970 .. D7978". I was going to do it myself but it seems only revision author can abandon it.
Thank you

Seems reasonable to me. I added code to do this in the normal kernel, but not in the tramp code because I didn't need it. Not sure your boot environment, but it certainly doesn't hurt anything and may help.

soutade_gmail.com added a comment to D6765: Linux ARM 8/16.

This patch is a simple copy of i386 implementation. Modifications made to machdep.c are done in patches 14 (https://reviews.freebsd.org/D6771) and 15 (https://reviews.freebsd.org/D6772).

Those patches should be merged with this. It makes it difficult to review something like this that should be considered a complete unit of work if it's split over multiple changes.

Much of this seems to be copied from the i386 support, is it needed on arm? e.g. places it calls i386 specific functions.

I was talking about linux_machdep.c.
