We are still tracking a moving target on Blackfin, and 2.3 has been
ported to the project's CVS head which defines the missing symbols.
Please use ksrc/arch/blackfin/ipipe-bf53x-CVS-20061215-1.6-00 over a
kernel extracted from the Blackfin CVS/SVN as of this date instead.
Actually, 1.4-03 should have been removed from the patch series.
