+【Issue#1389 動作確認】
+□ テスト内容
+本Issueの対応で、sysinfo()と/proc/meminfo の下記項目においてMcKernelの情報を
+返すようにした。
+[sysinfo]
+  totalram : rusage_global の total_memory
+  freeram : rusage_global の total_memory - usage_memory
+  mem_unit : 常に1
+[/proc/meminfo]
+  MemTotal : rusage_global の total_memory
+  MemFree : rusage_global の total_memory - usage_memory
+  SwapTotal : 常に0
+  SwapFree : 常に0
+  CommitLimit : rusage_global の total_memory - usage_memory
+  Committed_AS : rusage_global の usage_memory
+
+1. 本Issueで対応したsysinfo() と /proc/meminfo の値が想定どおりとなっていることを確認
+McKernelへのメモリ割り当てを 10G@0,10G@1 とした状態で下記プログラムを実行
+C1389T01: sysinfo() で取得される値が下記のとおりであることを確認
+  totalram : 20GiB * 0.95 以上、20GiB 未満であること
+  freeram : totralram * 0.95 以上、totalram 未満であること
+  mem_unit : 1 であること
+C1389T02: /proc/meminfo から取得される値が下記のとおりであることを確認
+  MemTotal : 20GiB * 0.95 以上、20GiB 未満であること
+  MemFree : MemTotal * 0.95 以上、MemTotal 未満であること
+  SwapTotal : 0 であること
+  SwapFree : 0 であること
+  CommitLimit : MemFreeと同値であること
+  Committed_AS : MemTotal - MemFree と同値であること
+
+2. 本Issueで対応したsysinfo() の項目を利用する以下のLTPを実行し、PASSすることを確認
+  - mtest01 -p80
+  - mtest01 -p80 -w
+  - mem01
+
+□ 実行手順
+$ make test
+
+McKernelのインストール先や、OSTEST, LTPの配置場所は、
+$HOME/.mck_test_config を参照している
+.mck_test_config は、McKernelをビルドした際に生成されるmck_test_config.sample ファイルを
+$HOMEにコピーし、適宜編集する
+
+□ 実行結果
+x86_64_result.log aarch64_result.log 参照。
+すべての項目をPASSしていることを確認。
