Merge remote-tracking branch 'remotes/agraf/tags/signed-ppc-for-upstream' into staging

Patch queue for ppc - 2015-09-20

Highlights this time around:

  - e500: Fix u-boot boot with -M virt by updating to new version
  - e500: fix ATMU reads
  - book3s: Fixes (unaligned exceptions, vector instructions)
  - yet another dbdma ide fix

I'm out taking care of my son for the next 2 months. During that time
please consider David Gibson the interim ppc queue maintainer. I'm sure
Aurelien will be more than happy to help him review patches as well ;-).
