[PATCH 16/34] riscv: Use CONFIG_PREEMPTION

From: Sebastian Andrzej Siewior
Date: Tue Oct 15 2019 - 15:20:33 EST


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 over to use CONFIG_PREEMPTION.
