Kernexec is there to "to make KERNEXEC/amd64 almost as good as it is on i386"; it ensures that, for example, user-space pages are not executable by the kernel.
Latent_entropy tries to generate entropy (randomness) from the kernel's execution; more on this one below.
Randomize_layout reorganizes structure layout randomly.
Rap implements grsecurity's "return address protection" mechanism, described in this presentation [PDF].
Size_overflow (described on this page) detects some integer overflows.
