All related error/warning messages:

cc1: all warnings being treated as errors

The global functions eeh_pe_get() and eeh_pe_get_parent() will be used
by subsequent patches. I think ppc/next merged 23 patches for EEH core
this time. I'm not sure I should refactor those patches to avoid the
build failure? :-)

I guess it's not your fault.. I have rules to filter out
"unused-function" warnings, however in your case all warnings are
turned into errors.. Although I can filter such errors too, they will
still present as bisect holes.

Thanks,
