So, this commit in -tip, combined with Linus's latest 
(v3.17-rc5), produces this build failure or arch/parisc 
defconfig:

/home/mingo/tip/arch/parisc/kernel/ptrace.c: In function 'do_syscall_trace_enter':
/home/mingo/tip/arch/parisc/kernel/ptrace.c:274: error: implicit declaration of function 'secure_computing'
make[2]: *** [arch/parisc/kernel/ptrace.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [arch/parisc/kernel] Error 2

My guess is that the interaction was caused by:

  c90f06943e05 parisc: Wire up seccomp, getrandom and memfd_create syscalls

Thanks,
