Message-Id: <20190528104848.13160-6-valentin.schneider@arm.com> Date: Tue, 28 May 2019 11:48:46 +0100 From: Valentin Schneider <valentin.schneider@....com> To: linux-kernel@...r.kernel.org Cc: Palmer Dabbelt <palmer@...ive.com>, Albert Ou <aou@...s.berkeley.edu>, linux-riscv@...ts.infradead.org Subject: [PATCH RESEND 5/7] RISC-V: 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.
