Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/lliubbo/blackfin

Pull blackfin changes from Bob Liu:
 "The biggest change was added an new processor(bf60x series).

  Bf60x series processor of blackfin can up to 1GHz with Hardware
  Support for HD Video Analytics, it use the same blackfin ISA but with
  some changes on system buses, interrupt controller and peripheral
  devices.

  Added dir arch/blackfin/mach-bf609/ and did some changes to the
  framework made linux working fine on the reference board bf609-ezkit
  now."
