kbuild: do not warn when unwind sections references .init/.exit sections
Andrew Morton reported a number of false positives for ia64 - like these: WARNING: drivers/acpi/button.o - Section mismatch: reference to .init.text: from .IA_64.unwind.init.text after '' (at offset 0x0) WARNING: drivers/acpi/button.o - Section mismatch: reference to .exit.text: from .IA_64.unwind.exit.text after '' (at offset 0x0) WARNING: drivers/acpi/processor.o - Section mismatch: reference to .init.text: from .IA_64.unwind after '' (at offset 0x1e8) They are all false positives - or at least the .c code looks OK. It is not known why sometimes a section name is appended and sometimes not. Fix is to accept references from all sections that includes "unwind." in the name.
