Merge tag 'v3.3-rc2' into depends/rmk/for-armsoc
There were conflicts between fixes going in after 3.3-rc1 and Russell's stable arm-soc base branch. Resolving it in the dependency branch so that each topic branch shares the same resolution. Conflicts: arch/arm/mach-at91/at91cap9.c arch/arm/mach-at91/at91sam9g45.c
