Subject[PATCH 05/34] c6x: Use CONFIG_PREEMPTION
Date
From: Thomas Gleixner <tglx@linutronix.de>

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT.
Both PREEMPT and PREEMPT_RT require the same functionality which today
depends on CONFIG_PREEMPT.

Switch the entry code over to use CONFIG_PREEMPTION.
