OK, I'll send the patch series for prefaulting and
porting memcpy_64.S to perf bench later.
This series do some dirty things especially in Makefile
of perf and defining ENTRY(). So I'd like to hear your comment.
Could you review these?

And I have another problem. I cannot see the name of
memcpy based on rep prefix because the symbol of it is ".Lmemcpy_c".
It seems that the symbol name start from "." cannot be seen
from other object files. So I have to seek the way to
find the name of rep memcpy...

Thanks,
	Hitoshi
