Pull parisc updates from Helge Deller:
 "The majority of the patches are reverts of previous commits regarding
  the parisc-specific low level spinlocking code and barrier handling,
  with which we tried to fix CPU stalls on our build servers. In the end
  John David Anglin found the culprit: We missed a define for
  atomic64_set_release(). This seems to have fixed our issues, so now
  it's good to remove the unnecessary code again.

  Other than that it's trivial stuff: Spelling fixes, constifications
  and such"
