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."
