arm64: hyperv: Initialize hypervisor on bootAdd ARM64-specific code to initialize the Hyper-Vhypervisor when booting as a guest VM.This code is built only when CONFIG_HYPERV is enabled.Signed-off-by: Michael Kelley Acked-by: Marc Zyngier Acked-by: Mark Rutland Acked-by: Catalin Marinas Link: https://lore.kernel.org/r/1628092359-61351-4-git-send-email-mikelley@microsoft.comSigned-off-by: Wei Liu List of files: /linux-6.15/arch/arm64/hyperv/Makefile

arm64: hyperv: Add Hyper-V hypercall and register access utilitieshyperv-tlfs.h defines Hyper-V interfaces from the Hyper-V Top LevelFunctional Spec (TLFS), and #includes the architecture-independentpart of hyperv-tlfs.h in include/asm-generic. The published TLFSis distinctly oriented to x86/x64, so the ARM64-specifichyperv-tlfs.h includes information for ARM64 that is not yet formallypublished. The TLFS is available here: docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfsmshyperv.h defines Linux-specific structures and routines forinteracting with Hyper-V on ARM64, and #includes the architecture-independent part of mshyperv.h in include/asm-generic.Use these definitions to provide utility functions to makeHyper-V hypercalls and to get and set Hyper-V providedregisters associated with a virtual processor.Signed-off-by: Michael Kelley Reviewed-by: Sunil Muthuswamy Acked-by: Marc Zyngier Acked-by: Mark Rutland Acked-by: Catalin Marinas Link: https://lore.kernel.org/r/1628092359-61351-2-git-send-email-mikelley@microsoft.comSigned-off-by: Wei Liu List of files: /linux-6.15/arch/arm64/hyperv/Makefile
