+	1. mmap で32MBの領域を確保
+	2. 下記条件でmremapを実行
+		- old_addr : mmapで確保したアドレス
+		- old_size : 0x2000000 (32MB)
+		- new_size : 0x3000000 (64MB)
+		- flags    : MREMAP_MAYMOVE
+	3. mremap がMAP_FAILED以外の値を返す
+	4. mremap がerrnoを設定しない

+		- new_size : 0x800000  (8MB)
+		- flags    : 0
+	3. mremap がold_addr に指定した値を返す
+	4. mremap がerrnoを設定しない
+
+CT_003: old/new_size 不正時の動作

+	2. 下記条件でmremapを実行
+		- old_addr : mmapで確保したアドレス
+		- old_size : 0xffffffffffffe000 (remap後の領域がアドレス空間の最大値を超える値)
+		- new_size : 0xffffffffffffe000 (remap後の領域がアドレス空間の最大値を超える値)
+		- flags    : 0
+	3. mremap がold_addr に指定した値を返す
+	4. mremap がerrnoを設定しない
+
+CT_004: old/new_size 不正時の動作

+		- flags    : MREMAP_MAYMOVE | MREMAP_FIXED
+		- new_addr : mmapで確保したアドレス + 0x40000000 (1GB)
+	3. mremap がMAP_FAILED を返す
+	4. mremap がerrnoにEINVALを設定する

+	3. mremap がMAP_FAILED を返す
+	4. mremap がerrnoにENOMEMを設定する
+
+□ 実行手順
+$ make test
+
+実行できない場合は、C1112.shの以下の行を適切に書き換えた後に実行。
+BIN=          mcexec が存在するパス
+SBIN=         mcreboot.sh が存在するパス
+OSTEST=       OSTESTが存在するパス
+
+□ 実行結果
+result.log 参照。
+すべての項目をPASSしていることを確認。
