Hmmm - I wonder if my tree is screwed up in some weird way. I'm seeing link warnings as well: AS .tmp_kallsyms2.o LD vmlinux SYSMAP System.map SYSMAP .tmp_System.map MODPOST vmlinux WARNING: init/built-in.o - Section mismatch: reference to .init.data: from .sdata after 'root_mountflags' (at offset 0x38) WARNING: init/built-in.o - Section mismatch: reference to .init.data:ino from .sdata after 'root_mountflags' (at offset 0x40) WARNING: arch/ia64/kernel/built-in.o - Section mismatch: reference to .init.data:smp_boot_data from .sdata before 'acpi_irq_model' (at offset -0x0) WARNING: arch/ia64/kernel/built-in.o - Section mismatch: reference to .init.data:rsvd_region from .sdata between 'ia64_sal' (at offset 0x118) and 'ia64_i_cache_stride_shift' WARNING: arch/ia64/kernel/built-in.o - Section mismatch: reference to .init.data:smp_boot_data from .sdata between 'cpu.25267' (at offset0x2e8) and 'sal_state_for_booting_cpu' WARNING: arch/ia64/mm/built-in.o - Section mismatch: reference to .init.data: from .sdata between 'hpage_shift' (at offset 0x50) and 'first_time.25897' WARNING: arch/ia64/mm/built-in.o - Section mismatch: reference to .init.data: from .sdata between 'hpage_shift' (at offset 0x68) and 'first_time.25897' WARNING: arch/ia64/mm/built-in.o - Section mismatch: reference to .init.data: from .sdata between 'hpage_shift' (at offset 0x70) and 'first_time.25897' WARNING: arch/ia64/mm/built-in.o - Section mismatch: reference to .init.data: from .sdata between 'hpage_shift' (at offset 0x88) and 'first_time.25897' WARNING: arch/ia64/mm/built-in.o - Section mismatch: reference to .init.data: from .sdata between 'hpage_shift' (at offset 0x90) and 'first_time.25897' ..... There's more errors, but they are all section mismatch warnings. I tried a make mrproper to see if that would fix but it didn't....
