This isn't an appropriate header file for exporting something from core
mm - what happens if arch/mn10300 wants it?.

I guess include/linux/mm.h is the place.

Rusty already suggested this. My bad.  Reason for adding it here was
that, I did the performance test for this platform. Will change and send
it out.

Thanks for review
