Merge branch 'next/fixes-non-critical' into next/drivers

Conflicts:
	arch/arm/mach-lpc32xx/clock.c
	arch/arm/mach-pxa/pxa25x.c
	arch/arm/mach-pxa/pxa27x.c

The conflicts with pxa are non-obvious, we have multiple branches
adding and removing the same clock settings. According to
Haojian Zhuang, removing the sa1100 rtc dummy clock is the correct
fix here.
