The individual iommu driver reports the iommu page faults by calling iommu_report_device_fault(), where a pre-registered device fault handler is called to route the fault to another fault handler installed on the corresponding iommu domain. The pre-registered device fault handler is static and won't be dynamic as the fault handler is eventually per iommu domain. Replace calling device fault handler with iommu_queue_iopf(). After this replacement, the registering and unregistering fault handler interfaces are not needed anywhere. Remove the interfaces and the related data structures to avoid dead code. Convert cookie parameter of iommu_queue_iopf() into a device pointer that is really passed.

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.
