Don't do it yourself, but once you introduce the new header it becomes a
no-brainer to switch the declarations to use it. So let's plan the new
header to make that switch easy.

Using trailing commas unconditionally would be okay, i.e.

#define X86_OP(func) .func = vmx_##func,
#include "kvm-x86-ops.h"

and leave out the terminator/delimiter in kvm-x86-ops.h. This is
similar to how we use vmx/vmcs_shadow_fields.h:

#define SHADOW_FIELD_RO(x, y) { x, offsetof(struct vmcs12, y) },
#include "vmcs_shadow_fields.h"

#define SHADOW_FIELD_RW(x, y) case x:
#include "vmcs_shadow_fields.h"

Thanks,

Paolo
