Adds support for 16GB hugepage size. To use this page size use kernel parameters as: default_hugepagesz=16G hugepagesz=16G hugepages=10 Testing: Tested with the stream benchmark which allocates 48G of arrays backed by 16G hugepages and does RW operation on them in parallel.

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.
