The code should be in a mergeable state after each patch. If only
patches 1-3 were merged, the code would be in an inconsistent state,
with some functions having confusing ENTRY/SYM_FUNC_END pairs. That
complicates git history and also makes it harder to review each patch.

It would be cleaner to separate things out. First, convert ENTRY/END
functions to use ENDPROC, which is a minor bug fix. Then they can be
converted to the new SYM_FUNC_START/END macros in a separate patch.
