With 4 levels of 16KB pages, we get this warning about the fact that we are copying a whole page into an array that is declared as having only two pointers for the top level of the page table: arch/arm64/mm/mmu.c: In function 'paging_init': arch/arm64/mm/mmu.c:528:2: error: 'memcpy' writing 16384 bytes into a region of size 16 overflows the destination [-Werror=stringop-overflow=] This is harmless since we actually reserve a whole page in the definition of the array that comes from, and just the extern declaration is short. The pgdir is initialized to zero either way, so copying the actual entries here seems like the best solution.

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.
