mainlining shenanigans
Right now the only point where softpin mappings get removed from the MMU context is when the mapped GEM object is destroyed. However, userspace might want to reuse that address space before the object is destroyed, which is a valid usage, as long as all mapping in that region of the address space are no longer used by any GPU jobs. Implement reaping of idle MMU mappings that would otherwise prevent the insertion of a softpin mapping.

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.
