## Summary armv8-m: report concrete CPU model in cpuinfo The ARMv8-M cpuinfo output always used the generic ARMv8-M model string even when the selected architecture was a concrete Cortex-M CPU. This makes Cortex-M85 targets appear less specific than the build configuration already knows them to be. Add compile-time model strings for the supported ARMv8-M Cortex-M variants and report Cortex-M55/Cortex-M85 as ARMv8.1-M cores. Also advertise PACBTI in the feature list when CONFIG_ARM_PACBTI is enabled so /proc/cpuinfo reflects the selected branch protection capability.
