Subject: [PATCH v4 07/11] KVM: arm64: selftests: Make vgic_init/vm_gic_create version agnostic
Date: Mon,  4 Oct 2021 18:19:17 -0700	[thread overview]
Message-ID: <20211005011921.437353-8-ricarkol@google.com> (raw)
In-Reply-To: <20211005011921.437353-1-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.
