Subject: [PATCH v3 21/21] KVM: arm64: Make __pkvm_create_mappings static
Date: Thu, 29 Jul 2021 14:28:18 +0100	[thread overview]
Message-ID: <20210729132818.4091769-22-qperret@google.com> (raw)
In-Reply-To: <20210729132818.4091769-1-qperret@google.com>

The __pkvm_create_mappings() function is no longer used outside of
nvhe/mm.c, make it static.
