    Subject[PATCH v19 093/130] KVM: TDX: Implements vcpu request_immediate_exit
    Date
    From: Isaku Yamahata <isaku.yamahata@intel.com>

    Now we are able to inject interrupts into TDX vcpu, it's ready to block TDX
    vcpu. Wire up kvm x86 methods for blocking/unblocking vcpu for TDX. To
    unblock on pending events, request immediate exit methods is also needed.
