Kernel: Crash on memory access in non-readable regions
...
This patch makes it possible to make memory regions non-readable.
This is enforced using the "present" bit in the page tables.
A process that hits an not-present page fault in a non-readable
region will be crashed.

Kernel: Disallow syscalls from writeable memory
...
Processes will now crash with SIGSEGV if they attempt making a syscall
from PROT_WRITE memory.
This neat idea comes from OpenBSD. :^)
