Hi Herbert, We have been using binutils v2.19. Can you please recommend the version(s) of binutils (gas) that we should test with before submitting a patch? V2.16.1, or perhaps the older version (2.12) described in /Documentation/Changes? We will retest with the recommended version, update the code and resubmit the patch ASAP.

However it doesn't build: AS [M] arch/x86/crypto/aesni-intel_asm.o arch/x86/crypto/aesni-intel_asm.S: Assembler messages: arch/x86/crypto/aesni-intel_asm.S:803: Error: no such instruction: `aesenc 16*1(%rdi),%xmm6' arch/x86/crypto/aesni-intel_asm.S:803: Error: no such instruction: `aesenc 16*1(%rdi),%xmm7' arch/x86/crypto/aesni-intel_asm.S:803: Error: no such instruction: `aesenc 16*1(%rdi),%xmm8' ... I suppose you can't rely on these new binutils instructions just yet.
