Allow to pass a remap argument to the swiotlb initialization functions to handle the Xen/x86 remap case. ARM/ARM64 never did any remapping from xen_swiotlb_fixup, so we don't even need that quirk.quoted
Aside from that the rest looks OK. Also, you can add my: Tested-by: Stefano Stabellini <sstabellini@kernel.org>Not for me, I fail to boot with [ 52.202000] bnxt_en 0000:31:00.0: swiotlb buffer is full (sz: 256 bytes), total 0 (slots), used 0 (slots) (this is iscsi root so I need the NIC). I bisected it to "x86: remove the IOMMU table infrastructure" but haven't actually looked at the code yet.
Again, this is as dom0. Baremetal is fine. -boris
