Thanks all, I saw the patch has been merged and is part of rc4. I'm
removing it from the fedora package.

At the moment I kept it as part of 6.2.0 build, which I am just about to push
to rawhide. It builds locally, and I am only waiting for the scratch-build to
finish.


Yes looks like we need to keep it, and get it upstream too.


Whoops.  That dropped through the cracks.
I'll queue that now-ish.

Ah right, I was supposed to test your kernel and never got there.
Plus it never got any r-b's.

Rebase was smooth and regression testing went ok on cortex-a57 host.

Yes, I saw that your original patch had been replaced by this new one I
mentioned, so I thought it was the correct solution, but I could not find
this new one on the repository as well.

At the moment I kept it as part of 6.2.0 build, which I am just about to
push to rawhide. It builds locally, and I am only waiting for the
scratch-build to finish.

 The patch I posted wasn't correct (or meant to be), it was just a
 workaround.  However I think you're right - I don't believe the
 original problem was ever fixed.

Yes, I saw that your original patch had been replaced by this new
one I mentioned, so I thought it was the correct solution, but I
could not find this new one on the repository as well.


Oh I see, it was indeed replaced by Richard Henderson's patch:

https://src.fedoraproject.org/rpms/qemu/blob/rawhide/f/0001-tcg-arm-Reduce-vector-alignment-requirement-for-NEON.patch


At the moment I kept it as part of 6.2.0 build, which I am just about to push

Yes looks like we need to keep it, and get it upstream too.

Oh I see, it was indeed replaced by Richard Henderson's patch:

Yes looks like we need to keep it, and get it upstream too.

The patch I posted wasn't correct (or meant to be), it was just a
workaround.  However I think you're right - I don't believe the
original problem was ever fixed.

Let's see what upstreams says ...
