Pull powerpc updates from Benjamin Herrenschmidt:
 "Here are the powerpc goodies for 3.5.  Main highlights are:

   - Support for the NX crypto engine in Power7+
   - A bunch of Anton goodness, including some micro optimization of our
     syscall entry on Power7
   - I converted a pile of our thermal control drivers to the new i2c
     APIs (essentially turning the old therm_pm72 into a proper set of
     windfarm drivers).  That's one more step toward removing the
     deprecated i2c APIs, there's still a few drivers to fix, but we are
     getting close
   - kexec/kdump support for 47x embedded cores

  The big missing thing here is no updates from Freescale.  Not sure
  what's up here, but with Kumar not working for them anymore things are
  a bit in a state of flux in that area."
