Containing hypervisor ABI definitions to use in mshv driver. Version numbers for each file: hvhdk.h 25212 hvhdk_mini.h 25294 hvgdk.h 25125 hvgdk_mini.h 25294 These are unstable interfaces and as such must be compiled independently from published interfaces found in hyperv-tlfs.h. These are in uapi because they will be used in the mshv ioctl API.
