Indeed. I should just have verified with the kernel command line, but
I started bisecting when it wasn't entirely obvious what was going on,
so I just finished it.

Commit 4bf7fda4dce2 ("iommu/dma: Add config for PCI SAC address
trick") is reverted in my tree. You can try again in a decade or so,
but at least on x86-64, that config option is basically a "stop modern
machines from working", and I don't want to have that even as an
option.

If somebody wants some debug output to figure out which device it is
that cares, send me a patch, but we're not trying this thing as-is
again.

Linus
