reading @ the patch thread, http://tinyurl.com/yjnj6wa

for reference ... checking in opensuse's src trees,

cd /usr/src
find . | grep x86 | grep time | grep xen | grep "\.c"$
./arch/x86/kernel/time_32-xen.c
./arch/x86/xen/time.c

time_32-xen.c is posted -> http://pastebin.com/f72c6de07
time.c  -> http://pastebin.com/f3b4a7fdd

checking in xen.git's pvops tree,
find . | grep x86 | grep time | grep xen | grep "\.c"$
  ./arch/x86/xen/time.c

-> http://pastebin.com/f3409ea7a.
