+    x86: wrong register was used in align macro
+    
+    New ALIGN_DESTINATION macro has sad typo: r8d register was used instead
+    of ecx in fixup section. This can be considered as a regression.
+    
+    Register ecx was also wrongly loaded with value in r8d in
+    copy_user_nocache routine.
+

+Backported to Debian's 2.6.18 by dann frazier <dannf at debian.org>
