Subject: [PULL kvm-unit-tests 29/39] arm/arm64: gic: Introduce setup_irq() helper
Date: Sat,  4 Apr 2020 16:37:21 +0200	[thread overview]
Message-ID: <20200404143731.208138-30-drjones@redhat.com> (raw)
In-Reply-To: <20200404143731.208138-1-drjones@redhat.com>

From: Eric Auger <eric.auger@redhat.com>

ipi_enable() code would be reusable for other interrupts
than IPI. Let's rename it setup_irq() and pass an interrupt
handler pointer.
