In case it matters, you can check for GC

Hi all,
This series adds API for 128-bit memory IO access and enables it for ARM64.
The original motivation for 128-bit API came from new Cavium network device
driver. The hardware requires 128-bit access to make things work. See
description in patch 3 for details.
