Subject: [PATCH 4/4] x86/hyperv: KVM: Rename "hv_enlightenments" to "hv_vmcb_enlightenments"
Now that KVM isn't littered with "struct hv_enlightenments" casts, rename
the struct to "hv_vmcb_enlightenments" to highlight the fact that the
struct is specifically for SVM's VMCB.
No functional change intended.
