Subject: [PATCH v2 7/7] KVM: arm64: Use symbolic names for the PMU versions
Date: Mon, 25 Jan 2021 12:26:38 +0000	[thread overview]
Message-ID: <20210125122638.2947058-8-maz@kernel.org> (raw)
In-Reply-To: <20210125122638.2947058-1-maz@kernel.org>

Instead of using a bunch of magic numbers, use the existing definitions
that have been added since 8673e02e58410 ("arm64: perf: Add support
for ARMv8.5-PMU 64-bit counters")
