Linux kernel source tree
3377e227af
Some users must have 4K pages while needing a 48-bit VA space size. The cleanest way do do this is to go to a 4-level page table for this case. Each page table level using order-0 pages adds 9 bits to the VA size (at 4K pages, so for four levels we get 9 * 4 + 12 == 48-bits. For the 4K page size case only we add support functions for the PUD level of the page table tree, also the TLB exception handlers get an extra level of tree walk.

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.
