Honestly I don't really like this part of the patch: it adds complexity to an already complex area. EFI_[UN]CACHED_OFFSET areas are id-mapped. So why can't the tlb miss be handled directly in the ivt (like we do for id-mapped Xen area) ? Maybe I don't really understand the issues so do not hesitate to explain!
