45C/C++ on netbsd/amd64 can reuse the same mapping:
46 * The address space starts from 0x1000 (option with 0x0) and ends with
47 0x7f7ffffff000.
48 * LoAppMem-kHeapMemEnd can be reused as it is.
49 * No VDSO support.
50 * No MidAppMem region.
51 * No additional HeapMem region.
52 * HiAppMem contains the stack, loader, shared libraries and heap.
53 * Stack on NetBSD/amd64 has prereserved 128MB.
54 * Heap grows downwards (top-down).
55 * ASLR must be disabled per-process or globally.
