-Subject: [PATCH 3/3] ARM: KVM: Check KVM_CAP_ARM_IRQ_LINE_LAYOUT_2 for
- smp_cpus > 256
-
-Host kernel within [4.18, 5.3] report an erroneous KVM_MAX_VCPUS=512
-for ARM. The actual capability to instantiate more than 256 vcpus
-was fixed in 5.4 with the upgrade of the KVM_IRQ_LINE ABI to support
-vcpu id encoded on 12 bits instead of 8 and a redistributor consuming
-a single KVM IO device instead of 2.
-
-So let's check this capability when attempting to use more than 256
-vcpus within any ARM kvm accelerated machine.

-(cherry-picked from commit fff9f5558d0e0813d4f80bfe1602acf225eca4fd)
-[yu: Use the legacy smp_cpus instead of ms->smp.cpus, as we don't have
-     struct CpuTopology in MachineState at that time. See commit
-     edeeec911702 for details.]
