This patch maps the new page to user space applications to allow converting a user space completion timestamp to system wall time at the lowest possible latency cost. By using a versioning scheme we allow compatibility between current and future userspace libraries. The change moves mlx5_ib_mmap_cmd enum from mlx5_ib.h to the abi header file mlx5-abi.h.

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.
