    Description

      The CRC32 hardware support for s390x is only available on z13 processors and later and require a Linux kernel version which support the vector extensions. Until VX runtime detection is added to WiredTiger, MongoDB builds will need to disable hardware crc32 support via --use-s390x-crc32=off.
