Subject: [PATCH v3 5/5] KVM: arm/arm64: Advertise support for KVM_CAP_ARM_USER_IRQ
Date: Wed,  5 Apr 2017 11:28:15 +0200	[thread overview]
Message-ID: <20170405092815.22503-6-cdall@linaro.org> (raw)
In-Reply-To: <20170405092815.22503-1-cdall@linaro.org>

From: Christoffer Dall <christoffer.dall@linaro.org>

Now when we support both the virtual timer and PMU reporting interrupts
to userspace, we can advertise this support.
