Subject: [PATCH seccomp v2 2/8] parisc: Enable seccomp architecture tracking
Date:   Wed, 11 Nov 2020 07:33:48 -0600
Message-Id: <9bb86c546eda753adf5270425e7353202dbce87c.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 parisc.
