From fdc5569eaba997852e0bfb57d11af496e4c1fa9a Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 24 Oct 2019 18:04:58 +0200 Subject: [PATCH] sched/rt, powerpc: Use CONFIG_PREEMPTION 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.
