Merge branch 'samsung/dt' into next/dt

* samsung/dt: (3 commit)
  Merge branch 'depends/rmk/for-linus' into samsung/dt
  Merge branch 'depends/rmk/restart' into next/cleanup
  Merge branch 'next/cleanup' into samsung/dt

Conflicts:
	arch/arm/mach-tegra/board-dt.c
	arch/arm/mach-tegra/include/mach/entry-macro.S

The latest version of the samsung/dt branch resolves
all sorts of conflicts with the latest upstream, no functional
changes that are not already there.
