+Subject: [PATCH 23/54] Fix the calculation of high word in a long long 64-bit
+
+    This patch will change the calculation of high word in a long long 64-bit.
+    Earlier to this patch the high word of long long word (0xF0000000ULL) is
+    coming to be 0xFFFFFFFF and low word is 0xF0000000. Instead the high word
+    should be 0x00000000 and the low word should be 0xF0000000. This patch
+    removes the condition of checking high word = 0 & low word < 0.
+    This check is not required for the correctness of calculating 32-bit high
+    and low words in a 64-bit long long.
