Merge tag 'upstream-3.6-rc1' of git://git.infradead.org/linux-ubi

Pull UBI changes from Artem Bityutskiy:
 "Change the default amount of eraseblocks which UBI reserves for bad
  block handling from 1% to 2%, because 1% does not meet most modern
  flash requirements.  1% was good enough in the past for old
  high-quality SLCs, but nowadays 2% is much more appropriate.:

Other changes are clean-ups.
