Subject: [patch 04/10] x86/traps: Remove pointless irq enable from do_spurious_interrupt_bug()
Date: Tue, 25 Feb 2020 22:36:40 +0100 [thread overview]
Message-ID: <20200225220216.518575042@linutronix.de> (raw)
In-Reply-To: 20200225213636.689276920@linutronix.de
From: Thomas Gleixner <tglx@linutronix.de>
That function returns immediately after conditionally reenabling interrupts which
is more than pointless and requires the ASM code to disable interrupts again.
