arm64: Build infrastructure This patch adds Makefile and Kconfig files required for building an AArch64 kernel.

arm64: Add CONFIG_DEBUG_SET_MODULE_RONX support In a similar fashion to other architecture, add the infrastructure and Kconfig to enable DEBUG_SET_MODULE_RONX support. When enabled, module ranges will be marked read-only/no-execute as appropriate.

ARM64: mm: HugeTLB support. Add huge page support to ARM64, different huge page sizes are supported depending on the size of normal pages: PAGE_SIZE is 4KB: 2MB - (pmds) these can be allocated at any time. 1024MB - (puds) usually allocated on bootup with the command line with something like: hugepagesz=1G hugepages=6 PAGE_SIZE is 64KB: 512MB - (pmds) usually allocated on bootup via command line.

arm64: dump: Make ptdump debugfs a separate option ptdump_register currently initializes a set of page table information and registers debugfs. There are uses for the ptdump option without wanting the debugfs options. Split this out to make it a separate option.

arm64, numa: Add NUMA support for arm64 platforms. Attempt to get the memory and CPU NUMA node via of_numa. If that fails, default the dummy NUMA node and map all memory and CPUs to node 0.

arm64: add KASAN support This patch adds arch specific code for kernel address sanitizer (see Documentation/kasan.txt). 1/8 of kernel addresses reserved for shadow memory. There was no big enough hole for this, so virtual addresses for shadow were stolen from vmalloc area. At early boot stage the whole shadow region populated with just one physical page (kasan_zero_page). Later, this page reused as readonly zero shadow for some memory that KASan currently don't track (vmalloc). After mapping the physical memory, pages for shadow memory are allocated and mapped. Functions like memset/memmove/memcpy do a lot of memory accesses. If bad pointer passed to one of these function it is important to catch this. Compiler's instrumentation cannot do this since these functions are written in assembly. KASan replaces memory functions with manually instrumented variants. Original functions declared as weak symbols so strong definitions in mm/kasan/kasan.c could replace them. Original functions have aliases with '__' prefix in name, so we could call non-instrumented variant if needed. Some files built without kasan instrumentation (e.g. mm/slub.c). Original mem* function replaced (via #define) with prefixed variants to disable memory access checks for such files.
