  vfio: Add support for mmapping sub-page MMIO BARs (2016-10-31 09:53:04 -0600)

----------------------------------------------------------------
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)

----------------------------------------------------------------
Alex Williamson (3):
      memory: Replace skip_dump flag with "ram_device"
      memory: Don't use memcpy for ram_device regions
      vfio: Handle zero-length sparse mmap ranges

Ido Yariv (1):
      vfio/pci: fix out-of-sync BAR information on reset

Yongji Xie (1):
      vfio: Add support for mmapping sub-page MMIO BARs
