    Merge remote-tracking branch 
'remotes/awilliam/tags/vfio-updates-20161031.0' into staging
    
    VFIO updates 2016-10-31
    
     - Replace skip_dump with ram_device to denote device memory and mark
       as non-direct to avoid memcpy to MMIO - fixes RTL (Alex Williamson)
     - Skip zero-length sparse mmaps - avoids unnecessary warning
       (Alex Williamson)
     - Clear BARs on reset so guest doesn't assume programming on return
       from S3 (Ido Yariv)
     - Enable sub-page MMIO mmaps - performance improvement for devices
       with smaller BARs, iff both host and guest map them to full,
       aligned pages (Yongji Xie)

      vfio: Handle zero-length sparse mmap ranges
      memory: Don't use memcpy for ram_device regions
      memory: Replace skip_dump flag with "ram_device"
