Hey All, I've updated this patch to the latest HEAD. This patch is a preparatory patch for ASLR. It makes it so that PS_STRINGS, USRSTACK, the VDSO, and the signal trampolining code pointers are all stored per-process. Going forward, with HardenedBSD's ASLR patch, these values will be modified to introduce randomness/entropy. The goal with this patch is to allow randomization of the stack base address and the VDSO.
