This patch moves UTS_RELEASE into its own header which is explicitly
included in only the files that really use UTS_RELEASE. module.h uses
a new field (KERNEL_VERSION_STRING) which has been added to version.h.
With this patch, a change to EXTRAVERSION no longer recompiles 95% of
your kernel.
The only significant changes are to module.h and Makefile. The rest of
the patch is adding #include <linux/uts_release.h> in those files that
use UTS_RELEASE. I suspect some of those files really only need
KERNEL_VERSION_STRING but that has been left as an exercise for the
file owners. Some of those files may no longer required version.h,
again that has been left for the file owners.
Do not backport this change to 2.[024]. Their builds have incomplete
dependency trees, some changes to the top level Makefile only work as a
lucky side effect of the extra recompiles.
