Subject: [PATCH 1/2] arm64: Enable seccomp architecture tracking
Date: Tue, 27 Oct 2020 17:19:59 -0700 [thread overview]
Message-ID: <20201028002000.2666043-2-keescook@chromium.org> (raw)
In-Reply-To: <20201028002000.2666043-1-keescook@chromium.org>
To enable seccomp constant action bitmaps, we need to have a static
mapping to the audit architecture and system call table size. Add these
for arm64.
