Subject: [PATCH 5/6] s390: simplify one-level sysctl registration for page_table_sysctl
Date:   Fri, 10 Mar 2023 15:45:24 -0800

Precedence: bulk

There is no need to declare an extra tables to just create directory,
this can be easily be done with a prefix path with register_sysctl().

Simplify this registration.
