Commit 2cbe23e3 authored by Arnd Bergmann's avatar Arnd Bergmann

Merge branch 'tegra/cleanups' into next/timer

Conflicts:
	arch/arm/mach-tegra/Makefile
	arch/arm/mach-vexpress/core.h

The tegra Makefile was changed in four different branches
in the same line. This merge should reduce the amount
of churn.
