From: Pierre Morel
Subject: [PATCH v1 8/9] s390x: numa: define drawers and books for NUMA
Date: Wed, 14 Jul 2021 18:53:15 +0200

S390 uses 5 levels of CPU topology, we implement the four lower levels:
drawers, books, sockets and cores.

Until now drawers and books were not defined, this patch add the
definition for drawers and books to the machine.
