The kernel page table splitting code will split page tables even for features the CPU does not support. E.g. a CPU may not support the NX feature. In order to avoid this, remove those bits from the flags parameter that correlate with unsupported CPU features within __set_memory(). In addition add an early exit if the flags parameter does not have any bits set afterwards.

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.
