+Subject: [PATCH] arm/cpu: Fixed function undefined error at compile time under
+ arm
+
+    Add the compilation option CONFIG_KVM while using
+    "kvm_arm_cpu_feature_supported" and "kvm_arm_get_one_reg".
+    In arm, the default value of CONFIG_KVM is no.
+
+    While the target is arm, the compilation fails because
+    the function "kvm_arm_cpu_feature_supporte" is declared
+    or the function "kvm_arm_get_one_reg" is not defined.
