Not for me, I fail to boot with

I bisected it to "x86: remove the IOMMU table infrastructure" but haven't
actually looked at the code yet.
That looks like the swiotlb buffer did not get initialized at all, but I
can't really explain why.
Can you stick in a printk and see if xen_swiotlb_init_early gets called
at all?
Actually, that's the only thing I did do so far and yes, it does get called.
