    Subject[PATCH v6 05/16] powerpc: Skip objtool from running on drivers/crypto/vmx/aesp8-ppc.o
    Date
    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.
