Qemu before version 2.11 does not implement the architecture correctly, and does not allow for a mask size of size different than 4. This patch introduces a compatibility mode for such systems, forcing the mask sizes to 4. Since the mask size is currently still 4 anyway, this patch should have no impact whatsoever by itself, but it will be needed when the mask size is increased to 64 bits in the next patch.

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.
