These 2 fields track whether user process has used Altivec/VSX
registers or not. They are used by kernel to setup signal frame
on user stack correctly regarding vector part.

CRIU(Checkpoint and Restore In User space) builds signal frame
for restored process. It will need this export information to
setup signal frame correctly. And CRIU will need to restore these
2 fields for the restored process.

Just a kind reminder per our previous discussion.
If possible, please help pull this in during 4.8 merge window. Some CRIU work items are pending for it.

Have a nice day.
