* physically contiguous memory regions it is mapping into page sizes

*
* Traditionally the IOMMU core just handed us the mappings directly,
* after making sure the size is an order of a 4KiB page and that the
* mapping has natural alignment.
*
* To retain this behavior, we currently advertise that we support
* all page sizes that are an order of 4KiB.
*
* If at some point we'd like to utilize the IOMMU core's new behavior,
* we could change this to advertise the real page sizes we support.

* 512GB Pages are not supported due to a hardware bug
