Subject: [RFC PATCH 2/7] KVM: arm/arm64: Move kvm_vgic_flush_hwstate under disabled irq
Date: Sat, 10 Dec 2016 21:47:07 +0100 [thread overview]
Message-ID: <20161210204712.21830-3-christoffer.dall@linaro.org> (raw)
In-Reply-To: <20161210204712.21830-1-christoffer.dall@linaro.org>
As we are about to play tricks with the timer to be more lazy in saving
and restoring state, we need to move the timer flush function under a
disabled irq section and since we hav to flush the vgic state after the
timer state, move it as well.
