Yeah, that makes it all even simpler, thanks!
We're still b0rked though:
arch/x86/crypto/crct10dif-pcl-asm_64.S: Assembler messages:
arch/x86/crypto/crct10dif-pcl-asm_64.S:147: Error: no such instruction: `pclmulqdq $0x0,%xmm10,%xmm0'
arch/x86/crypto/crct10dif-pcl-asm_64.S:148: Error: no such instruction: `pclmulqdq $0x11,%xmm10,%xmm8'
arch/x86/crypto/crct10dif-pcl-asm_64.S:149: Error: no such instruction: `pclmulqdq $0x0,%xmm10,%xmm1'
...
and need checking for more instructions. I'll play with this more
tomorrow.
Good night :-)
