From 1c137323e9a2a970b4a5bf8cf3c50e0ea1cefbeb Mon Sep 17 00:00:00 2001 From: Sathvika Vasireddy Date: Mon, 14 Nov 2022 23:27:43 +0530 Subject: crypto: vmx: Skip objtool from running on aesp8-ppc.o With objtool enabled, below warnings are seen when trying to build: drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: aes_p8_set_encrypt_key+0x44: unannotated intra-function call drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: .text+0x2448: unannotated intra-function call drivers/crypto/vmx/aesp8-ppc.o: warning: objtool: .text+0x2d68: unannotated intra-function call Skip objtool from running on drivers/crypto/vmx/aesp8-ppc.o file for the following reasons: - Since this file comes from OpenSSL, and since it is a perl file which generates a .S file, it may not be the best choice to make too many code changes to such files, unless absolutely necessary. - As far as the objtool --mcount functionality is concerned, we do not have to run objtool on this file because there are no calls to _mcount().
