I'm not familiar with what Xen does but why can't Xen just override

Why does Xen need to hook BIOVEC_PHYS_MERGEABLE to the iommu_bio_merge
parameter (as this patch does)? BIOVEC_PHYS_MERGEABLE and the
iommu_bio_merge parameter are not related at all.

No, it doesn't. It was convenient to reuse that mechanism, but I can easily re-add something else (which would be more or less identical).
