Commit 920cf4194954ec ("drm/i915: Introduce an internal allocator for disposable private objects") introduced a regression for the kernel running as Xen dom0: when switching to graphics mode a GPU HANG occurred. Reason seems to be a missing adaption similar to that done in commit 7453c549f5f648 ("swiotlb: Export swiotlb_max_segment to users") to i915_gem_object_get_pages_internal(). So limit the maximum page order to be used according to the maximum swiotlb segment size instead to the complete swiotlb size.
