NOMMU build leads to the following error:

drivers/pci/mmap.c:60:3: error: implicit declaration of function 'pgprot_device' [-Werror=implicit-function-declaration]
vma->vm_page_prot = pgprot_device(vma->vm_page_prot);

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.
