objtool throws the following unannotated intra-function call warnings: arch/powerpc/kernel/entry_64.o: warning: objtool: .text+0x4: unannotated intra-function call arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xe64: unannotated intra-function call arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xee4: unannotated intra-function call Fix these warnings by annotating intra-function call, using ANNOTATE_INTRA_FUNCTION_CALL macro, to indicate that the branch targets are valid.
