Re: MODPOST section mismatches

From: Steve Heflin <hidden>

To reproduce the problem and see the details on section mismatches:

     make ARCH=powerpc sequoia_defconfig

     make ARCH=powerpc CONFIG_DEBUG_SECTION_MISMATCH=y

while building vmlinux.o the MODPOST warns about 8 section mismatches.
WARNING: modpost: Found 8 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'

After modifying the make launch to include the recommended option
shown above, I see that the section mismatch warning is due to data
structures containing the address of initialization modules which
have the __init attribute. Since the memory model is FLAT, is this a problem?

thanks,
Steve
