My solution to this issue:
The check_arm_cpu_feature function is used to check CPU features on ARM
architecture. Since __ARM_ARCH is specific to ARM and these features are
not present on RISC-V, this code needs to be ignored in non-ARM
environments. A conditional check can be added to ensure that this ARM
feature detection code is not compiled on non-ARM architectures.I have
tested this solution locally,and it works well.The debpatch is in the
attachment.Please let me know whether this solution can be accepted.
