Subject: [PATCH v3 06/10] KVM: arm64: selftests: Make vgic_init/vm_gic_create version agnostic
Date: Tue, 28 Sep 2021 11:48:00 -0700	[thread overview]
Message-ID: <20210928184803.2496885-7-ricarkol@google.com> (raw)
In-Reply-To: <20210928184803.2496885-1-ricarkol@google.com>

Make vm_gic_create GIC version agnostic in the vgic_init test. Also
add a nr_vcpus arg into it instead of defaulting to NR_VCPUS.

No functional change.
