Thanks, but this was not what I was really looking for. However,
searching for 'randomize_va_space' led me to a thread on lkml started by
Arjan van de Ven on January 27th, 2005:
http://lkml.org/lkml/2005/1/27/56

It would be great if someone can provide more details on this subject:
  1) when was randomize_va_space introduced? (probably somewhere in
2.6.11.x)
  2) when was it enabled by default (2.6.12.? but no announcement in
changelog?)
  3) which additions were added in later releases? (and when?)

Thanks,
Victor
