[PATCH v1 0/6] arm64: Support for 2022 data processing instructions

[Mark Brown]

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.

Mark Brown (6):
  arm64/hwcap: Add support for FEAT_CSSC
  kselftest/arm64: Add FEAT_CSSC to the hwcap selftest
  arm64/hwcap: Add support for FEAT_RPRFM
  kselftest/arm64: Add FEAT_RPRFM to the hwcap test
  arm64/hwcap: Add support for SVE 2.1
  kselftest/arm64: Add SVE 2.1 to hwcap test
