[PATCH] Randomisation: stack randomisation
The patch below replaces the existing 8Kb randomisation of the userspace stack
pointer (which is currently only done for Hyperthreaded P-IVs) with a more
general randomisation over a 64Kb range. 64Kb is not a lot, but it's a start
and once the dust settles we can increase this value to a more agressive
value.
