- * kvm_mmu_gva_to_gpa() - Translate a Guest Virtual Address to a Guest Physical Address.
- * @vcpu:   The vCPU state, containing MMU configuration (TTBR0_EL1, etc.).
- * @gva:    The Guest Virtual Address to translate.
- * @gpa:    A pointer to store the resulting Guest Physical Address.
- *
- * This function is the entry point for the emulated MMU.
- *
- * For now, this is a stub that implements identity mapping (GVA -> GPA)
- * when the MMU is disabled, which is the correct architectural behavior
- * on reset.
- *
- * Return: 0 on success, or a negative error code on a fault.
