For building linux-next with allmodconfig by upstream gcc5, at present, I
found 2 issues totally, and report them to upstream gcc bugzilla:

- For stacktrace.c issue:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65804
"blackfin: Not support global frame pointer with -fno-omit-frame-pointer"

- For coredump issues (for duplication reason, only report one, now):

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65803
"blackfin: internal compiler error: segment fault linux kernel"

At least, I shall try to fix the coredump issues within this month (
although at present, I guess, I can not send patch v1 for it within
2015-04-20).


Thanks.
