----------------------------------------------------------------
Major additions:
- sysctl and seccomp operation to discover available actions. (tyhicks)
- new per-filter configurable logging infrastructure and sysctl. (tyhicks)
- SECCOMP_RET_LOG to log allowed syscalls. (tyhicks)
- SECCOMP_RET_KILL_PROCESS as the new strictest possible action.
- self-tests for new behaviors.

      seccomp: Introduce SECCOMP_RET_KILL_PROCESS
      seccomp: Implement SECCOMP_RET_KILL_PROCESS action
      selftests/seccomp: Test thread vs process killing

Tyler Hicks (6):
      seccomp: Sysctl to display available actions
      seccomp: Operation for checking if an action is available
      seccomp: Sysctl to configure actions that are allowed to be logged
