Subject: [PATCH v3 05/16] powerpc: Skip objtool from running on drivers/crypto/vmx/aesp8-ppc.o
Date: Mon, 12 Sep 2022 13:50:09 +0530	[thread overview]
Message-ID: <20220912082020.226755-6-sv@linux.ibm.com> (raw)
In-Reply-To: <20220912082020.226755-1-sv@linux.ibm.com>

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.
