During very early development of the Xe driver the force_execlist module parameter could be used to exercise some parts of the driver in a GuC-less manner. This was primarily intended to ensure that the driver was being designed and developed with proper modularity and layering; use of the GuC firmware has always been considered mandatory for any real Xe driver operation. The "execlist" implementation in the driver was never completed, and has further bitrotted over time to the point where it hangs during execution of even the simplest IGT tests like xe_exec_store now. Drop the force_execlist parameter; it's broken and isn't going to get fixed. In the (very unlikely) event that we decide to bring something like this back in the future, it would need to be as a per-device configfs setting rather than a driver-wide module parameter. The "execlist" implementation is now dead code, so it will probably also be removed sometime in the near future. There's a bit more general refactoring we might want to do first before we take that step, so for now we're just removing the module parameter.
