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.
