[NSWI004] Test for debug_get_stack_pointer relaxed

[Richard Hladík]

> looking at your progress with the kernel assignment, we have realized
> that one of the tests for the debug_get_stack_pointer function is a
> bit naive, and as a result fails for some otherwise acceptable
> implementations of debug_get_stack_pointer. We have updated the test
> in GitLab, if you have run into this problem and see the test fail
> with "reading $sp does not change it", you can e.g. rebase on the
> update as follows:
> 
> git remote add upstream git at gitlab.mff.cuni.cz:teaching/nswi004/winter-2019-20/templates/01-introduction-to-kernel.git
> git fetch upstream
> git rebase upstream/master

You may also have to (or at least I had to) force-push the next time
you are pushing:

	git push --force
