Sorry, this somehow got omitted from the assignment text but it remained 
in the tests. Because this is my mistake, we will not penalize you if 
you do not implement %pF at all (though I highly recommend you to do so 
as it could be very useful later on).

%pF is another extension (like %pL) that prints first four instructions 
of a given function (i.e. parameter is a function pointer). Format is 
given in the test, as with %pL this is mostly a debugging feature.

Updated text is already in the upstream repository.


Also note that assignment tests are again split into two groups: base 
and extended. It serves as another hint of what is the more and less 
important part of the assignment (e.g. in A01, implementing %pL is less 
important than implementing %x).

Generally, incomplete base part means that you will not be able to 
continue towards next assignment (because you would miss a core 
functionality). If you do not implement the extended part, you would 
receive less points and working with your kernel could become a bit less 
developer-friendly (e.g. missing debugging features or slower execution).
