This patch adds sys$msyscall() which is loosely based on an OpenBSD mechanism for preventing syscalls from non-blessed memory regions. It works similarly to pledge and unveil, you can call it as many times as you like, and when you're finished, you call it with a null pointer and it will stop accepting new regions from then on. If a syscall later happens and doesn't originate from one of the previously blessed regions, the kernel will simply crash the process.
