Hi Christian,

Thanks for the additional info! Confirm that with the PPA the proposed
checks now pass:

$ echo "vmovaps 0x40(,%rax,1),%zmm0" | as --64 -o avx.o && objdump -d avx.o | 
grep vmovaps
  8:   0: 62 f1 7c 48 28 04 05    vmovaps 0x40(,%rax,1),%zmm0


Also the proposed OVS automake build-system changes will enable avx512 
correctly:
checking binutils avx512 assembler checks passing... yes

I'll wait for the SRU team to accept into proposed. Regards, -Harry
