I'm seeing the following warning:
WARNING: vmlinux.o(.init.text+0x1acdc): Section mismatch:
reference to
.exit.text:gfar_mdio_exit (between 'gfar_init' and 'gfar_mdio_init')
I don't understand why its not ok to access .exit.text
from .init.text
Several architectures discards .exit.text in the final linker
script (arch/$(ARCH)/kernel/vmlinux.lds.S
So any references to .exit.text will when a module is build-in result
in a linker error because ld will flag it as an error when we
reference
a symbol in a discarded section.
For the popular architectures (i386,x86_64) we discard .exit.text at
runtime so here we do not see the error from ld (sadly).
Fair point, wondering what we do with .exit on PPC, another thing for
the list :)
