Upstream has decided to make -testing patches private, effectively ceasing free support for grsecurity/PaX [1]. Consequently, we can no longer responsibly support grsecurity on NixOS. This patch turns the kernel and patch expressions into build errors and adds a warning to the manual, but retains most of the infrastructure, in an effort to make the transition smoother. For 17.09 all of it should probably be pruned. [1]: https://grsecurity.net/passing_the_baton.php
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at http://nixos.org/nixos and in the manual in doc/manual.
