The current checks for the __IOMMU_DOMAIN_PAGING capability seem a bit stifled, since it is quite likely now that a non-paging domain won't have a pgsize_bitmap and/or mapping ops, and thus get caught by the earlier condition anyway. Swap them around to test the more fundamental condition first, then we can reasonably also upgrade the other to a WARN_ON, since if a driver does ever expose a paging domain without the means to actually page, it's clearly very broken.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
