In commit957870f934("drm/i915: Split out i915_gem_object_set_tiling()"), I swapped an alignment check for IS_ALIGNED and in the process removed the less-than check. That check turns out to be important as it was the only rejection for stride == 0. Tvrtko did spot it, but I was overconfident in the IS_ALIGNED() conversion.

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.
