Subject: [PATCH v2 2/9] c6x: entry: Remove unneeded need_resched() loop
Date: Mon, 23 Sep 2019 15:36:13 +0100 [thread overview]
Message-ID: <20190923143620.29334-3-valentin.schneider@arm.com> (raw)
In-Reply-To: <20190923143620.29334-1-valentin.schneider@arm.com>
Since the enabling and disabling of IRQs within preempt_schedule_irq()
is contained in a need_resched() loop, we don't need the outer arch
code loop.
Acked-by: Mark Salter <msalter@redhat.com>
