Heiko Carstens e7615c9225 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.
