Subject: [PATCH seccomp v2 6/8] sh: Enable seccomp architecture tracking
Date:   Wed, 11 Nov 2020 07:33:52 -0600
Message-Id: <61ae084cd4783b9b50860d9dedb4a348cf1b7b6f.1605101222.git.yifeifz2@illinois.edu>

From: YiFei Zhu <yifeifz2@illinois.edu>

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 sh.
