Subject: [PATCH v1 4/9] s390x: Topology list entries and SYSIB 15.x.x
Date: Wed, 14 Jul 2021 18:53:11 +0200 [thread overview]
Message-ID: <1626281596-31061-5-git-send-email-pmorel@linux.ibm.com> (raw)
In-Reply-To: <1626281596-31061-1-git-send-email-pmorel@linux.ibm.com>
We define the CPU type Topology List Entry and the
Container type Topology List Entry to implement SYSIB 15.1.x
This patch will be squatched with the next patch.
