Thomas Huth a0ed5d4b01 s390: enable ARCH_HAS_MEMBARRIER_SYNC_CORE 
JIRA: https://issues.redhat.com/browse/RHEL-54248

commit e7615c9225d7c7562d1cd95ba8cc2cbf38c3d29e
Author: Heiko Carstens <hca@linux.ibm.com>
Date:   Fri Mar 17 10:31:40 2023 +0100

    s390: enable ARCH_HAS_MEMBARRIER_SYNC_CORE

    s390 trivially supports the ARCH_HAS_MEMBARRIER_SYNC_CORE requirements
    since the used lpswe(y) instruction to return from any kernel context to
    user space performs CPU serialization. This is very similar to arm, arm64
    and powerpc.

    See commit 70216e18e5 ("membarrier: Provide core serializing command,
    *_SYNC_CORE") for further details.
