+Description:   Identifies the subset of CPUs in the system that can execute
+               AArch32 (32-bit ARM) applications. If present, the same format as
+               /sys/devices/system/cpu/{offline,online,possible,present} is used.
+               If absent, then all or none of the CPUs can execute AArch32
+               applications and execve() will behave accordingly.
