Subject: [PATCH v2 0/9] Replace smp_read_barrier_depends() with lockless_derefrence()

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.

Pranith Kumar (9):
  doc: memory-barriers.txt: Document use of lockless_dereference()
  drivers: dma: Replace smp_read_barrier_depends() with
    lockless_dereference()
  dcache: Replace smp_read_barrier_depends() with lockless_dereference()
  hyperv: Replace smp_read_barrier_depends() with lockless_dereference()
  percpu: Replace smp_read_barrier_depends() with lockless_dereference()
  perf: Replace smp_read_barrier_depends() with lockless_dereference()
  seccomp: Replace smp_read_barrier_depends() with
    lockless_dereference()
  task_work: Replace smp_read_barrier_depends() with
    lockless_dereference()
  netfilter: Replace smp_read_barrier_depends() with
    lockless_dereference()
