Subject: [PATCH 5.9 062/105] sched/idle: Fix arch_cpu_idle() vs tracing
Date: Mon, 14 Dec 2020 18:28:36 +0100 [thread overview]
Message-ID: <20201214172558.254181807@linuxfoundation.org> (raw)
In-Reply-To: <20201214172555.280929671@linuxfoundation.org>
From: Peter Zijlstra <peterz@infradead.org>
[ Upstream commit 58c644ba512cfbc2e39b758dd979edd1d6d00e27 ]
We call arch_cpu_idle() with RCU disabled, but then use
local_irq_{en,dis}able(), which invokes tracing, which relies on RCU.
Switch all arch_cpu_idle() implementations to use
raw_local_irq_{en,dis}able() and carefully manage the
lockdep,rcu,tracing state like we do in entry.
(XXX: we really should change arch_cpu_idle() to not return with
interrupts enabled)
