I have some memory that I would like to never be paged out to VM. Do I
have to do anything special to make that happen? Or is that memory
already prevented from swapping?

Kernel memory is wired. That's why you should use as little as possible, since when you allocate kernel memory, you are eating a chunk of the kernel virtual address space, which is a scarce resource.
