SSSE6 / RAID6

Hi list,

I just compiled 3.4 for my little Atom box. Is there any way I can
confirm if the RAID6 check is using SSSE6 instructions?

$ zcat /proc/config.gz |grep -i -P '(raid|sss)'
CONFIG_RAID_ATTRS=y
CONFIG_MD_RAID0=m
CONFIG_MD_RAID1=m
CONFIG_MD_RAID10=m
CONFIG_MD_RAID456=y
# CONFIG_MULTICORE_RAID456 is not set
CONFIG_DM_RAID=m
CONFIG_ASYNC_RAID6_TEST=m
CONFIG_ASYNC_RAID6_RECOV=y
CONFIG_CRYPTO_SHA1_SSSE3=y
CONFIG_RAID6_PQ=y

 $ cat /proc/cpuinfo  |grep ssse

$ cat /proc/mdstat
