The 2022 update to the Arm architecture includes a number of additions of generic data processing features, covering the base architecture, SVE and SME. Other than SME these are all simple features which introduce no architectural state so we simply need to expose hwcaps for them. This series covers these simple features. Since the SME updates do introduce new architectural state for which we must add new ABI they will be handled in a separate series.
