Similar to Jan's concern, if bare-metal x86 people decide to have their own paddr_vmcoreinfo_note() (and they usually build with !CONFIG_XEN) we will have to update this again. I suppose we can deal with that if/when it happens since we will discover this immediately. Reviewed-by: Boris Ostrovsky <[email protected]>
