This series introduces initial flags and functionality for the fp8 feature.
Specifically, the following are added: - functions that enable constructing valid fpm register values. - support for the '+fp8' -march modifier that defines the __ARM_FEATURE_FP8 macro to 1. - support for reading and writing the new system register FPMR (Floating Point Mode Register) which configures the new FP8 features Tested against aarch64-unknown-linux-gnu. Due to the addition of new flags, this patch is based on and requires that the series "[PATCH v2 00/11] aarch64: Extend aarch64_feature_flags to 128 bits" be applied. Is this ok for master? I do not have merge permissions. Can someone merge this for me please?
