    Subject[RFC 12/16] arm64: kvm: Annotate non-standard stack frame functions
    Date
    Both __guest_entry and __guest_exit functions do not setup
    a correct stack frame. Because they can be considered as callable
    functions, even if they are particular cases, we chose to silence
    the warnings given by objtool by annotating them as non-standard.
