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
