[$] Randomizing structure layout

Kees Cook is working on a series of patchesfor C structure randomization to improve security in the Linuxkernel. This is an important part of obfuscating the internal binary layoutof a running kernel, making kernel exploits harder. The randstructplugin is a new GCC add-on that lets the compiler randomize the layout of Cstructures. Whenenabled, the plugin will scramble the layout of the kernel structures thatare specifically designated for randomization.
