Subject: [PATCH v2 07/20] arm: Stash kvm_vcpu_init for later use
Date: Tue, 20 Jun 2023 11:33:40 -0500	[thread overview]
Message-ID: <20230620163353.2688567-8-oliver.upton@linux.dev> (raw)
In-Reply-To: <20230620163353.2688567-1-oliver.upton@linux.dev>

A subsequent change will add support for resetting a vCPU, which
requires reissuing the KVM_ARM_VCPU_INIT ioctl. Save the kvm_vcpu_init
worked out for later use.
