Cannot compile kernel: problem with EXPORT_SYMBOL and EXPORT_SYMBOL_GPL symbols

[Dmitry Katsubo <dmitry.katsubo@gmail.com>]

Dear Debian community,

I am trying to recompile default kernel with one just option changed:

-CONFIG_NR_CPUS=32
+CONFIG_NR_CPUS=4

I get problems with symbols on all modules (the error log is really long):

How can I overcome this problem? Thanks in advance.

P.S.

There are many reports on similar problem in this maillist, but the the
ones I have looked through are connected with additional patches
applied. In my case there are extra patches: kernel package is used as
provided in repository, I just want to tune the config.

* Linux kernel 3.2.0-4, sources are installed with standard
  apt-get source linux-image-3.2.0-4-686-pae
* After all preparations, kernel was build for one target with
  fakeroot make -f debian/rules.gen binary-arch_i386_none_686-pae
* Kernel compiles OK with default config.
