Subject: [PATCH v2 2/7] KVM: mips: Use kvm_get_vcpu() instead of open-coded access
Date: Tue, 16 Nov 2021 16:03:58 +0000	[thread overview]
Message-ID: <20211116160403.4074052-3-maz@kernel.org> (raw)
In-Reply-To: <20211116160403.4074052-1-maz@kernel.org>

As we are about to change the way vcpus are allocated, mandate
the use of kvm_get_vcpu() instead of open-coding the access.
