+# Later on boot up, the kernel will read this list, save the locations and turn

 #
 # This is no easy feat. This script is called just after the original
 # object is compiled and before it is linked.
 #
-# The references to the call sites are offsets from the section of text
-# that the call site is in. Hence, all functions in a section that
-# has a call site to mcount, will have the offset from the beginning of

+# When parse this object file using 'objdump', the references to the call
+# sites are offsets from the section that the call site is in. Hence, all

+# offset from the beginning of the section and not the beginning of the
+# function.
+#
+# But where this section will reside finally in vmlinx is undetermined at
+# this point. So we can't use this kind of offsets to record the final
+# address of this call site.
+#
+# The trick is to change the call offset referring the start of a section to
+# referring a function symbol in this section. During the link step, 'ld' will
+# compute the final address according to the information we record.
 #
-# The trick is to find a way to record the beginning of the section.
-# The way we do this is to look at the first function in the section
-# which will also be the location of that section after final link.
 # e.g.
 #
 #  .section ".sched.text", "ax"
-#  .globl my_func
-#  my_func:
 #        [...]
-#        call mcount  (offset: 0x5)

+#        [...]
+#        call mcount  (offset: 0x10)
 #        [...]
 #        ret

+#  .globl fun2

+#  func3:
+#        [...]
+#        call mcount (offset: 0x30)
 #        [...]
 #
 # Both relocation offsets for the mcounts in the above example will be
-# offset from .sched.text. If we make another file called tmp.s with:
+# offset from .sched.text. If we choose global symbol func2 as a reference and
+# make another file called tmp.s with the new offsets:
 #
 #  .section __mcount_loc
-#  .quad  my_func + 0x5
-#  .quad  my_func + 0x1b
+#  .quad  func2 - 0x10
+#  .quad  func2 + 0x10
 #
-# We can then compile this tmp.s into tmp.o, and link it to the original
+# We can then compile this tmp.s into tmp.o, and link it back to the original
 # object.
 #
-# But this gets hard if my_func is not globl (a static function).
-# In such a case we have:
+# In our algorithm, we will choose the first global function we meet in this
+# section as the reference. But this gets hard if there is no global functions
+# in this section. In such a case we have to select a local one. E.g. func1:
 #
 #  .section ".sched.text", "ax"
-#  my_func:
+#  func1:
 #        [...]
-#        call mcount  (offset: 0x5)
+#        call mcount  (offset: 0x10)
 #        [...]
 #        ret
-#  other_func:
+#  func2:
 #        [...]
-#        call mcount (offset: 0x1b)
+#        call mcount (offset: 0x20)
 #        [...]
+#  .section "other.section"
 #
 # If we make the tmp.s the same as above, when we link together with
-# the original object, we will end up with two symbols for my_func:
+# the original object, we will end up with two symbols for func1:
 # one local, one global.  After final compile, we will end up with
-# an undefined reference to my_func.
+# an undefined reference to func1 or a wrong reference to another global
+# func1 in other files.
 #
 # Since local objects can reference local variables, we need to find
 # a way to make tmp.o reference the local objects of the original object
-# file after it is linked together. To do this, we convert the my_func
+# file after it is linked together. To do this, we convert func1
