Recently lockless_dereference() was added which can be used in place of
hard-coding smp_read_barrier_depends().
http://lkml.iu.edu/hypermail/linux/kernel/1410.3/04561.html
The following series tries to do this.
There are still some hard-coded locations which I was not sure how to replace
with. I will send in separate patches/questions regarding them.
