 	  - seccomp syscall wired up
 
-	  For best performance, an arch should use seccomp_phase1 and
-	  seccomp_phase2 directly.  It should call seccomp_phase1 for all
-	  syscalls if TIF_SECCOMP is set, but seccomp_phase1 does not
-	  need to be called from a ptrace-safe context.  It must then
-	  call seccomp_phase2 if seccomp_phase1 returns anything other
-	  than SECCOMP_PHASE1_OK or SECCOMP_PHASE1_SKIP.
-
-	  As an additional optimization, an arch may provide seccomp_data
-	  directly to seccomp_phase1; this avoids multiple calls
-	  to the syscall_xyz helpers for every syscall.
