per thread prctl commands to relax the syscall abi such that top bits of user pointers are ignored in the kernel. this allows the use of those bits by hwasan or by mte to color pointers and memory on aarch64: linux commit 63f0c60379650d82250f22e4cf4137ef3dc4f43d arm64: Introduce prctl() options to control the tagged user addresses ABI
