From: "Xin Li (Intel)" <[email protected]> Add ORIGINAL_EVENT_DATA and INJECTED_EVENT_DATA to the list of shadowed VMCS fields.
Shadowing these fields allows the L1 hypervisor to access them without triggering a VM-exit to L0, optimizing performance for nested virtualization workloads that frequently query or inject event data.
