Just a side note, for future reference, this title lacks a verb and is thus not self-describing: x86/efi: Runtime services virtual mapping It should probably have been something like: x86/efi: Implement and enable separate, stable virtual mapping for runtime services ? Chances are that it will be a popular bisection target ;-) Ingo
