Merge tag 'xtensa-next-20121008' of git://github.com/czankel/xtensa-linux

Pull Xtensa patchset from Chris Zankel:
 "The Xtensa tree has been broken for some time now, and this patchset
  brings it back to life.  It has been part of the linux-next tree for
  some time.

  Most changes are inside the xtensa subdirectory; the other changes
  mostly add another rule to already existing #ifdefs to exclude Xtensa,
  where required.  The only 'common' change is to add two more sections
  ('.xt.prop' and '.xt.lit') to the white list in modpost."
