This patch adds few wrapper to perform fixed_point_16_16 operations mul_round_up_u32_fixed16 : Multiplies u32 and fixed_16_16_t variables & returns u32 result with rounding-up. mul_fixed16 : Multiplies two fixed_16_16_t variable & returns fixed_16_16 div_round_up_fixed16 : Perform division operation on fixed_16_16_t variables & return u32 result with round-off div_round_up_u32_fixed16 : devide uint32_t variable by fixed_16_16 variable and round_up the result to uint32_t. These wrappers will be used by later patches in the series.

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.
