G4x cursor control registers still allow us to write to the pipe select bits even though cursors are supposed to be fixed to a specific pipe. Bspec tells us that we should only ever write 0 to these bits. Let's follow that recommendation. On ilk+ the bits become hardwired to 0. Also looks like ICL repurposes these bits for some other use, so we had better stop setting them to bogus values there.

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.
