Subject: [PATCH 0/2] Drivers: hv: Remove dependencies on guest page size

Hyper-V assumes page size to be 4KB. This might not be the case on ARM64
architecture. The first patch in this patchset introduces a hyer-v
specific function for allocating a zeroed page which can have a
different implementation on ARM64 to address the issue of different
guest and host page sizes. The second patch removes dependencies on
guest page size in vmbus by using hyper-v specific page symbol and
functions.
