Since commit 2aacdff entitled "cpufreq: Move common part from governors to
separate file", whenever the drivers that depend on this new file
(cpufreq_ondemand or cpufreq_conservative) are built as modules, a new module
named cpufreq_governor is created. It seems that kmake is smart enough to create
a separate module whenever more than one module includes the same object file.
As drivers/cpufreq/cpufreq_governor.c contains no MODULE directives, the
resulting module has no license specified, which results in logging of a "module
license 'unspecified' taints kernel". In addition, a number of globals are
exported GPL only, and are therefore not available.

This particular patch is the simplest possible; however, it hides the intent. I
have prepared the longer version that makes the reason clearer by adding a new
configuration variable that is dependent on the other two, and rearranges
drivers/cpufreq/Makefile. That version could be submitted if that is what is
desired. The changes to cpufreq_governor.c are the same as in this version.
