AFAICS it was broken even before 85a256d. Nevertheless, the patch is
correct, but conflicts with 0915512 in the kbuild tree. What about this
one?

Subject: [PATCH] Makefile: "make kernelrelease" should show the correct full kernel version

After commit 85a256d8e0116c8f5ad276730830f5d4d473344d, 'make kernelrelease'
doesn't show the correct full kernel version. This patch fixes it,
'make kernelrelease' will show the same version name with the one
you finally get.
