[PATCH v10 1/7] asm-generic: hyperv: Fix incorrect architecture dependencies
From: Michael Kelley <hidden>

Also in:
linux-efi, linux-hyperv, lkml
Subsystem:
generic include/asm header files, hyper-v/azure core and drivers, the rest, x86 architecture (32-bit and 64-bit) · Maintainers:
Arnd Bergmann, "K. Y. Srinivasan", Haiyang Zhang, Wei Liu, Dexuan Cui, Long Li, Linus Torvalds, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
Move the declaration of hv_root_partition and hyperv_pcpu_input_arg from the x86-specific mshyperv.h to the arch independent mshyperv.h since they are used by arch independent code. While here, add a missing #include needed to compile correctly on ARM64.
