Subject: [PATCH 4/4] ARM: mach-virt: Select PMUv3 driver by default
Date: Fri, 24 Mar 2017 12:15:29 +0000	[thread overview]
Message-ID: <20170324121529.22603-5-marc.zyngier@arm.com> (raw)
In-Reply-To: <20170324121529.22603-1-marc.zyngier@arm.com>

Since 32bit guests are not unlikely to run on an ARMv8 host,
let's select the PMUv3 driver, which allows the PMU to be used
on such systems.
