When wedging the hw, we want to mark all in-flight requests as -EIO. This is made slightly more complex by execlists who store the ready but not yet submitted-to-hw requests on a private queue (an rbtree priolist). Call into execlists to cancel not only the ELSP tracking for the submitted requests, but also the queue of unsubmitted requests. v2: Move the majority of engine_set_wedged to the backends (both legacy ringbuffer and execlists handling their own lists).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
