Some commands need rework for nesting, as they used to assume S1 and S2 are mutually exclusive: - CMD_TLBI_NH_ASID: Consider VMID if stage-2 is supported - CMD_TLBI_NH_ALL: Consider VMID if stage-2 is supported, otherwise invalidate everything, this required a new vmid invalidation function for stage-1 only (ASID >= 0) Also, rework trace events to reflect the new implementation.
