seccomp: Add a seccomp_data parameter secure_computing()
Currently, if arch code wants to supply seccomp_data directly to seccomp (which is generally much faster than having seccomp do it using the syscall_get_xyz() API), it has to use the two-phase seccomp hooks. Add it to the easy hooks, too. Cc: linux-arch@vger.kernel.org Signed-off-by: Andy Lutomirski <luto@kernel.org> Signed-off-by: Kees Cook <keescook@chromium.org>
