[PATCH 09/34] ia64: Use CONFIG_PREEMPTION

[Sebastian Andrzej Siewior]

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

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 and kprobes over to use CONFIG_PREEMPTION.
