The mm_exit() op will be removed from the SVA API. When a process dies and its mm goes away, the IOMMU driver won't notify device drivers anymore. Drivers should expect to handle a lot more aborted DMA. On the upside, it does greatly simplify the queue management. The uacce_mm struct, that tracks all queues bound to an mm, was only used by the mm_exit() callback. Remove it.

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.
