Space reserved for PKMap should span from PKMAP_BASE to FIXADDR_START. For large page sizes this is not the case as eg. for 64k pages the range currently defined is from 0xfe000000 to 0x102000000(!!) which obviously isn't right. Remove the hardcoded location and set the BASE address as an offset from FIXADDR_START. Since all PKMAP ptes have to be placed in a contiguous memory, ensure that this is the case by placing them all in a single page. This is achieved by aligning the end address to pkmap pages count pages.

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.
