Subject: [PATCH 07/24] KVM: arm64: Use cpus_have_final_cap for has_vhe()
Date: Fri, 29 May 2020 17:01:04 +0100 [thread overview]
Message-ID: <20200529160121.899083-8-maz@kernel.org> (raw)
In-Reply-To: <20200529160121.899083-1-maz@kernel.org>
By the time we start using the has_vhe() helper, we have long
discovered whether we are running VHE or not. It thus makes
sense to use cpus_have_final_cap() instead of cpus_have_const_cap(),
which leads to a small text size reduction.
