From 39014c45467f0a655ae77f98be549a0a4ba5cfe1 Mon Sep 17 00:00:00 2001 From: Valentin Schneider Date: Mon, 23 Sep 2019 15:36:16 +0100 Subject: microblaze: entry: Remove unneeded need_resched() loop 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.
