A previously introduced patch that prevented kbuild to attempt to sign an out-of-the-tree module only fixed this issue for cases when a full kernel tree was used for compiling. Using the kernel-devel package for compilation remained broken. This update allows out-of-the-tree modules to compile using the kernel-devel package only.

Reproduced with i686 .84.el6 also. Here is how systemtap is invoking a failing:
% cat Makefile
EXTRA_CFLAGS := -g -Wno-implicit-function-declaration -Werror
obj-m := tracequery_kmod_8.o
% make -C /lib/modules/2.6.32-84.el6.i686/build M=`pwd` modules ARCH=i386 V=1
It seems like a pretty vanilla kernel-devel-only sort of build.
The diff between a successful run (-44.2 kernel) and an unsuccessful one (-84):
