After changing INIT_UDATA_BUF_OR_NULL() to an inline function, this does the same change to INIT_UDATA for consistency. I'm keeping it separate as this part is much larger and we wouldn't want to backport this to stable kernels if we ever want to address the gcc warnings by backporting the first patch. Again, using an inline function gives us better type safety here among other issues with macros. I'm using u64_to_user_ptr() to convert the user pointer to simplify the logic rather than adding lots of new type casts.

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.
