Hyper-V folks, if the changes look ok I'd like to take this through the KVM tree as Vitaly has an in-progress KVM series[*] that conflicts mightily with these changes. The main goal of this series it to clean up KVM's ugly casting of the VMCB's software reserved field to the Hyper-V enlightenments struct, e.g. replace a bunch of code that does: (struct hv_enlightenments *)vmcb->control.reserved_sw; with: &vmcb->control.hv_enlightenments; That cleanup is complicated slightly due the Hyper-V enlightenments being "KVM private", versus the VMCB struct being "public", but that itself is also a "bug". The enlightenments come directly from the TLFS, i.e. aren't KVM internal. Moving the definition to hyperv-tlfs.h where it belongs has the happy side effect of making the struct visible to asm/svm.h. Compile tested only, but the resulting kvm-amd.ko binary is identical before and after the series.
