Subject: [PATCH 03/34 v3] powerpc: Use CONFIG_PREEMPTION
Date: Thu, 24 Oct 2019 18:04:58 +0200 [thread overview]
Message-ID: <20191024160458.vlnf3wlcyjl2ich7@linutronix.de> (raw)
In-Reply-To: <20191024135920.cp673ivbcomu2bgy@linutronix.de>
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.
