Linus Torvalds dd4e5d6106 Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb()) 
Remove mmiowb() from the kernel memory barrier API and instead, for
 architectures that need it, hide the barrier inside spin_unlock() when
 MMIO has been performed inside the critical section.

Pull mmiowb removal from Will Deacon:
 "Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())

  Remove mmiowb() from the kernel memory barrier API and instead, for
  architectures that need it, hide the barrier inside spin_unlock() when
  MMIO has been performed inside the critical section.

  The only relatively recent changes have been addressing review
  comments on the documentation, which is in a much better shape thanks
  to the efforts of Ben and Ingo.

  I was initially planning to split this into two pull requests so that
  you could run the coccinelle script yourself, however it's been plain
  sailing in linux-next so I've just included the whole lot here to keep
  things simple"
