Patch queue for ppc - 2015-09-20

Browse source 
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 ;-).
