Subject: [patch V2 03/17] x86/traps: Remove pointless irq enable from do_spurious_interrupt_bug()
Date: Wed, 23 Oct 2019 14:27:08 +0200 [thread overview]
Message-ID: <20191023123117.871608831@linutronix.de> (raw)
In-Reply-To: 20191023122705.198339581@linutronix.de
That function returns immediately after conditionally reenabling interrupts which
is more than pointless and requires the ASM code to disable interrupts again.
