[sparc32] unversioned udiv taints kernel

Hello,

I finally got some kernel-images for 2.6 built up on sparc32, but one 
thing I had to do to get stuff to fit the 2500KB limit was to break out 
scsi into modules and use an initial ramdisk. However:

$ dmesg | grep udiv
scsi_mod: no version for "udiv" found: kernel tainted.

This is the only such occurrence. arch/sparc/kernel/sparc_ksyms.c says:

EXPORT_SYMBOL(udiv);

Christoph Hellwig suggested EXPORT_SYMBOL_NOVERS but:

/* We don't mangle the actual symbol anymore, so no need for
  * special casing EXPORT_SYMBOL_NOVERS.  FIXME: Deprecated */
#define EXPORT_SYMBOL_NOVERS(sym) EXPORT_SYMBOL(sym)

What's the right way to fix this?

The versioning method has changed; all symbols are versioned now using
a different method.  I believe I had fixed this quite a while ago -
check the bk logs.  What kernel are you using?

2.6.8.1. It's reproducible any time core SCSI support is modularized.
