Linus Torvalds 3913d00ac5 A treewide cleanup of interrupt descriptor (ab)use with all sorts of racy 
accesses, inefficient and disfunctional code. The goal is to remove the
 export of irq_to_desc() to prevent these things from creeping up again.

Pull irq updates from Thomas Gleixner:
 "This is the second attempt after the first one failed miserably and
  got zapped to unblock the rest of the interrupt related patches.

  A treewide cleanup of interrupt descriptor (ab)use with all sorts of
  racy accesses, inefficient and disfunctional code. The goal is to
  remove the export of irq_to_desc() to prevent these things from
  creeping up again"
