Revision c15f5bbc94ece97831184abef664186278c93674 authored by Linus Torvalds on 03 October 2013, 15:54:39 UTC, committed by Linus Torvalds on 03 October 2013, 15:54:39 UTC
Pull powerpc fixes from Ben Herrenschmidt:
 "Here are a few powerpc fixes, all aimed at -stable, found in part
  thanks to the ramping up of a major distro testing and in part thanks
  to the LE guys hitting all sort interesting corner cases.

  The most scary are probably the register clobber issues in
  csum_partial_copy_generic(), especially since Anton even had a test
  case for that thing, which didn't manage to hit the bugs :-)

  Another highlight is that memory hotplug should work again with these
  fixes.

  Oh and the vio modalias one is worse than the cset implies as it
  upsets distro installers, so I've been told at least, which is why I'm
  shooting it to stable"

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc/tm: Switch out userspace PPR and DSCR sooner
  powerpc/tm: Turn interrupts hard off in tm_reclaim()
  powerpc/perf: Fix handling of FAB events
  powerpc/vio: Fix modalias_show return values
  powerpc/iommu: Use GFP_KERNEL instead of GFP_ATOMIC in iommu_init_table()
  powerpc/sysfs: Disable writing to PURR in guest mode
  powerpc: Restore registers on error exit from csum_partial_copy_generic()
  powerpc: Fix parameter clobber in csum_partial_copy_generic()
  powerpc: Fix memory hotplug with sparse vmemmap
