During execlist_context_deferred_alloc() we presumed that the context is uninitialised (we only just allocated the state object for it!) and chose to optimise away the later call to engine->init_context() if engine->init_context were NULL. This breaks with GVT's contexts that are marked as pre-initialised to avoid us annoyingly calling engine->init_context(). The fix is to not override ce->initialised if it is already true.

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.
