Merge tag 'upstream-3.7-rc1' of git://git.infradead.org/linux-ubi

Pull UBI changes from Artem Bityutskiy:
 "The main change is the way we reserve eraseblocks for bad blocks
  handling.  We used to reserve 2% of the partition, but now we are more
  aggressive and we reserve 2% of the entire chip, which is what
  actually manufacturers specify in data sheets.  We introduced an
  option to users to override the default, though.

  There are a couple of fixes as well, and a number of cleanups."
