+□ テスト内容
+
+arm64環境における/proc/cpuinfoについて、以下を確かめる。
+
+(1) "processor" フィールドが/sys/devices/system/cpu/onlineファイルが示す
+CPUの数だけ存在すること。
+(2) "processor" フィールドの値が0からはじまる連番であること。
+
+
+□ 実行手順
+
+(1) $HOME/.mck_test_configを、MCK_DIRがMcKernelのインストール先を指すように編集する
+(2) 以下を実行する
+
+$ make test
+
+
+□ 確認方法
+
+標準出力にSUCCESSが出力されること
