[PATCH 0/2] arm64: Add seccomp support

[AKASHI Takahiro]

This patch enables secure computing (system call filtering) on arm64.
System calls can be allowed or denied by loaded bpf-style rules.
Architecture specific part is to run secure_computing() on syscall entry
and check the result. See [1/2]

Prerequisites are:
 * "arm64: Add audit support" patch
 * "arm64: make a single hook to syscall_trace() for all syscall features" patch

This code is tested on ARMv8 fast model using libseccomp v2.1.1 with
modifications for arm64 and verified by its "live" tests, 20, 21 and 24.
