I suspect I'll have to revert this.

On arm64, I get a "writing 16 bytes into a region of size 0" in the Xe driver

drivers/gpu/drm/xe/xe_gt_pagefault.c:340

but I haven't looked into it much yet.

It's not some gcc-11 issue, though, this is with gcc version 13.2.1

It looks like the kernel test robot reported this too (for s390), at

https://lore.kernel.org/all/202401161031.hjGJHMiJ-lkp@xxxxxxxxx/T/

and in that case it was gcc-13.2.0.

So I don't think the issue is about gcc-11 at all, but about other
random details.
