This fixes below warnings in posttest with CONFIG_CRYPTO_SHA1_SSSE3=y.

With this change, test_get_len can decode it correctly. $ arch/x86/tools/test_get_len -v -y ffffffff810d6069: c5 f9 73 de 04 vpsrldq $0x4,%xmm6,%xmm0 Succeed: decoded and checked 1 instructions Reported-by: Ingo Molnar Signed-off-by: Masami Hiramatsu Cc: yrl.pp-manager.tt@hitachi.com Link: http://lkml.kernel.org/r/20120210053340.30429.73410.stgit@localhost.localdomain Signed-off-by: Ingo Molnar --- Reading git-diff-tree failed
