+    [PATCH] i386: Force data segment to be 4K aligned
+    
+    o Currently there is no specific alignment restriction in linker script
+      and in some cases it can be placed non 4K aligned addresses. This fails
+      kexec which checks that segment to be loaded is page aligned.
+    
+    o I guess, it does not harm data segment to be 4K aligned.
