       "Two regression fixes for md, one fairly recent and minor (diskstats

        I guess (almost) no-one uses non-power-of-2 chunks.

       "First batch of KVM changes for 4.1
      
        The most interesting bit here is irqfd/ioeventfd support for ARM and
        ARM64.
      
        Summary:
      
        ARM/ARM64:
           fixes for live migration, irqfd and ioeventfd support (enabling
           vhost, too), page aging
      
        s390:
           interrupt handling rework, allowing to inject all local interrupts
           via new ioctl and to get/set the full local irq state for migration
           and introspection.  New ioctls to access memory by virtual address,
           and to get/set the guest storage keys.  SIMD support.
      
        MIPS:
           FPU and MIPS SIMD Architecture (MSA) support.  Includes some
           patches from Ralf Baechle's MIPS tree.
      
        x86:
           bugfixes (notably for pvclock, the others are small) and cleanups.
           Another small latency improvement for the TSC deadline timer"
