Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Browse source 
Pull powerpc fixes from Benjamin Herrenschmidt:
 "Here are a few fixes for powerpc.  Note the addition to the generic
  irq.h.  This is part of a 3-patches regression fix for mpic due to
  changes in how IRQ_TYPE_NONE is being handled.  Thomas agreed to the
  addition of the new IRQ_TYPE_DEFAULT contant, however he hasn't
  replied with an Ack to the actual patch yet.  I don't to wait much
  longer with these patches tho."

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/mpic: Properly set default triggers
  irq: Add IRQ_TYPE_DEFAULT for use by PIC drivers
  powerpc/mpic: Fix confusion between hw_irq and virq
  powerpc/pmac: Don't add_timer() twice
  powerpc/eeh: Fix crash caused by null eeh_dev
  powerpc/mpc85xx: add MPIC message dts node
  powerpc/mpic_msgr: fix offset error when setting mer register
  powerpc/mpic_msgr: add lock for MPIC message global variable
  powerpc/mpic_msgr: fix compile error when SMP disabled
  powerpc: fix build when CONFIG_BOOKE_WDT is enabled
  powerpc/85xx: don't call of_platform_bus_probe() twice
