/*
 * We do NOT shadow fields that are modified when L0
 * traps and emulates any vmx instruction (e.g. VMPTRLD,
 * VMXON...) executed by L1.
 * For example, VM_INSTRUCTION_ERROR is read
 * by L1 if a vmx instruction fails (part of the error path).
 * Note the code assumes this logic. If for some reason
 * we start shadowing these fields then we need to
 * force a shadow sync when L0 emulates vmx instructions
 * (e.g. force a sync if VM_INSTRUCTION_ERROR is modified
 * by nested_vmx_failValid)
 *
 * When adding or removing fields here, note that shadowed
 * fields must always be synced by prepare_vmcs02, not just
 * prepare_vmcs02_rare.
 */

/*
 * Keeping the fields ordered by size is an attempt at improving
 * branch prediction in vmcs12_read_any and vmcs12_write_any.
