2007-08-27Blackfin arch: vmlinux.lds.S, break up our .init into separate sectionsMike Frysinger
Break up our .init into separate section like all other ports do and so that we dont mix text and data (causes disassembly headaches as pointed out by Robin) Cc: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>

the kconfig defines revise anomaly handling by basing things on the compiler not the kconfig defines, so the header is stable and usable outside of the kernel.
