The following commit has been merged into the sched/urgent branch of tip: Commit-ID: fdc5569eaba997852e0bfb57d11af496e4c1fa9a Gitweb: https://git.kernel.org/tip/fdc5569eaba997852e0bfb57d11af496e4c1fa9a Author: Thomas Gleixner <tglx@xxxxxxxxxxxxx> AuthorDate: Thu, 24 Oct 2019 18:04:58 +02:00 Committer: Ingo Molnar <mingo@xxxxxxxxxx> CommitterDate: Sun, 08 Dec 2019 14:37:32 +01:00 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.
