[PATCH 0/5] Add new headers for Hyper-V Dom0

[Nuno Das Neves]

To support Hyper-V Dom0 (aka Linux as root partition), many new
definitions are required.

The plan going forward is to directly import headers from
Hyper-V. This is a more maintainable way to import definitions
rather than via the TLFS doc. This patch series introduces
new headers (hvhdk.h, hvgdk.h, etc, see patch #3) directly
derived from Hyper-V code.

This patch series replaces hyperv-tlfs.h with hvhdk.h, but only
in Microsoft-maintained Hyper-V code where they are needed. This
leaves the existing hyperv-tlfs.h in use elsewhere - notably for
Hyper-V enlightenments on KVM guests.

An intermediary header "hv_defs.h" is introduced to conditionally
include either hyperv-tlfs.h or hvhdk.h. This is required because
several headers which today include hyperv-tlfs.h, are shared
between Hyper-V and KVM code (e.g. mshyperv.h).

Summary:
Patch 1-2: Cleanup patches
Patch 3: Add the new headers (hvhdk.h, etc..) in include/hyperv/
Patch 4: Add hv_defs.h and use it in mshyperv.h, svm.h,
         hyperv_timer.h
Patch 5: Switch to the new headers, only in Hyper-V code

Nuno Das Neves (5):
  hyperv: Move hv_connection_id to hyperv-tlfs.h
  hyperv: Remove unnecessary #includes
  hyperv: Add new Hyper-V headers
  hyperv: Add hv_defs.h to conditionally include hyperv-tlfs.h or
    hvhdk.h
  hyperv: Use hvhdk.h instead of hyperv-tlfs.h in Hyper-V code
