My frustration says please please please remove blackfin with sugar on
top. If you look at the new unified siginfo.h you will notice that
blackfin has the majority of conflicting si_code definitions.
Given that I have already dealt with the frustrating situations I can
wait a release or two. But even though I found a cross compiler for
blackfin there is a real cost to keeping it in the tree.
