Yeah, "dependency" is a bit ambiguous here. It can mean both "this
patch wont work without said patch" as well as "this patch wont apply
without said patch". Probably would have been better to say that it
won't apply to avoid the ambiguity.

Also, these types of notes are best stated after the '---' line. As
it's good information for the maintainer pulling in the patch, but
should not go in the change log. Same for comments like "Changes since
version 1 of this series".

That is:

i386 is already using kstack_end() in dumpstack_32.c.
We should also use it to make the code clearer and unify the stack
printing logic some more.

Note: This patch depends on patch "x86: fix output of show_stack_log_lvl()"
or it might not apply properly.

The change log for the above stops at the '---'.
