Notes: v2 -> v3: - Remove autoconf check for madvise; assume it always exists - ntdll/unix/virtual: fix code style - ntdll/unix/virtual: edit fixme message in prefetch_memory - ntdll/unix/virtual: validate addresses argument first in prefetch_memory - wow64/virtual: use ULongToPtr() macro - wow64/virtual: separate 32-bit and 64-bit variables in wow64_NtSetInformationVirtualMemory
