Subject: [PATCH 2/5] KVM: arm64: Move kvm_arch_vcpu_run_pid_change() out of line
Date: Fri, 15 Oct 2021 10:08:19 +0100	[thread overview]
Message-ID: <20211015090822.2994920-3-maz@kernel.org> (raw)
In-Reply-To: <20211015090822.2994920-1-maz@kernel.org>

Having kvm_arch_vcpu_run_pid_change() inline doesn't bring anything
to the table. Move it next to kvm_vcpu_first_run_init(), which will
be convenient for what is next to come.
