arm/arm64: KVM: Enable 32 bits kvm vcpu events support

gengdongjiu1 · Marc Zyngier · commit 58bf437ff64e · 2018-10-18T10:14:03.000+01:00
The commit 539aee0 ("KVM: arm64: Share the parts of get/set events useful to 32bit") shares the get/set events helper for arm64 and arm32, but forgot to share the cap extension code. User space will check whether KVM supports vcpu events by checking the KVM_CAP_VCPU_EVENTS extension Acked-by: James Morse <james.morse@arm.com> Reviewed-by : Suzuki K Poulose <suzuki.poulose@arm.com> Signed-off-by: Dongjiu Geng <gengdongjiu@huawei.com> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
