Error log:
arch/parisc/kernel/ptrace.c: In function 'do_syscall_trace_enter':
arch/parisc/kernel/ptrace.c:274:2: error: implicit declaration of function
'secure_computing' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[1]: *** [arch/parisc/kernel/ptrace.o] Error 1

Bisect points to commit 273299fb6380 ('Merge branch 'x86/seccomp') which
obviously doesn't help much. Suspected culprit is c90f06943e05 ('parisc: Wire up
seccomp, getrandom and memfd_create syscalls') which seems to be missing an
include file.
