Subject: [PATCH seccomp v2 7/8] xtensa: Enable seccomp architecture tracking
Date:   Wed, 11 Nov 2020 07:33:53 -0600
Message-Id: <79669648ba167d668ea6ffb4884250abcd5ed254.1605101222.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 xtensa.
