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

Pull a few more things for powerpc by Benjamin Herrenschmidt:
 - Anton's did some recent improvements to EPOW event reporting on
   pSeries (power supply failures and such).  The patches are self
   contained enough and replace really nasty code so I felt it should
   still go in
 - I did the vio driver registration change Greg requested, I don't see
   the point of leaving that til the next merge window
 - The remaining EEH changes I said were still pending to get rid of the
   EEH references from the generic struct device_node
 - A few more iSeries removal bits
 - A perf bug fix on 970

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/perf: Fix instruction address sampling on 970 and Power4
  powerpc+sparc/vio: Modernize driver registration
  powerpc: Random little legacy iSeries removal tidy ups
  powerpc: Remove NO_IRQ_IGNORE
  powerpc/pseries: Cut down on enthusiastic use of defines in RAS code
  powerpc/pseries: Clean up ras_error_interrupt code
  powerpc/pseries: Remove RTAS_POWERMGM_EVENTS
  powerpc/pseries: Use rtas_get_sensor in RAS code
  powerpc/pseries: Parse and handle EPOW interrupts
  powerpc: Make function that parses RTAS error logs global
  powerpc/eeh: Retrieve PHB from global list
  powerpc/eeh: Remove eeh information from pci_dn
  powerpc/eeh: Remove eeh device from OF node
