Subject: [PATCH] unhide CONFIG_DEBUG_SECTION_MISMATCH

Using: v2.6.25-rc1-120-ge760e71

In a normal compilation, I might this message:

...
  MODPOST vmlinux.o
WARNING: modpost: Found 4 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
...

I can indeed try to re-make, passing CONFIG_DEBUG_SECTION_MISMATCH=y on the
command line, but I can't turn on the option in my .config.  That's because
the option depends on "UNDEFINED".  (Was that an attempt to "hide" the
option?  Why?)  The following small patch allows me to set the option in my
.config.

Cheers,
Erez.
