drm_pci_alloc() refuses to cooperate if the passed alignment exceeds the object size. So round up the obj size to the next power of two as well to make this actually work. Obviously things work just fine as long as the size was a power of two to begin with. However kms_cursor_crc doesn't always use power of two sizes so we hit a failure when we try to allocate the phys memory.

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.
