Commit0f36a85c3b("drm/i915: Flush pending interrupt following a GPU reset") got confused and only applied the flush to the set-wedge path (which itself is proving troublesome), but we also need the serialisation on the regular reset path. Oops. Move the interrupt into reset_irq() and make it common to the reset and final set-wedge. v2: reset_irq() after port cancellation, as we assert that execlists->active is sane for cancellation (and is being reset by reset_irq).

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.
