The Hyper-V uses 4k page size regardless of system page size.

This patchset fixes issues while running on systems with page sizes other than 4k.

Long Li (4):
  bus/vmbus: Align ring buffer data region to system page boundary
  bus/vmbus: Define Hyper-V page size
  bus/vmbus: Use Hyper-V page size for mapping to UIO pages
  net/netvsc: Use Hyper-V page size for the driver
