Subject: [PATCH 0/5] Add noncoherent platform support for vop driver 

Change the way of allocating vring to support noncoherent platform for vop
driver, and add some related dma changes to make sure noncoherent platform works
well. 

Sherry Sun (5):
  misc: vop: change the way of allocating vring for noncoherent platform
  misc: vop: change the way of allocating used ring
  misc: vop: simply return the saved dma address instead of virt_to_phys
  misc: vop: set VIRTIO_F_ACCESS_PLATFORM for nocoherent platform
  misc: vop: mapping kernel memory to user space as noncached
