Subject: [PATCH -tip 0/4] A few updates around smp_store_mb()

Hi,

Other than Peter's recent rename of set_mb to reflect the SMP
ordering nature of the call, there really hasn't updates that
further reflect this. Here are some pretty straightforward
updates, but ultimately wonder if we cannot make the call the
same for all archs; which is where we seem to be headed _anyway_,
more of this in Patch 3 which updates x86.

Patch 1 is just one a snuck in while looking at arch code.

Only tested on the x86 bits.

Thanks!

Davidlohr Bueso (4):
  arch,cmpxchg: Remove tas() definitions
  arch,barrier: Use smp barriers in smp_store_release()
  x86,asm: Re-work smp_store_mb()
  doc,smp: Remove ambiguous statement in smp_store_mb()
