The kernel version is set via these config options via scripts/setlocalversion:
CONFIG_LOCALVERSION
CONFIG_LOCALVERSION_AUTO
In your setup, CONFIG_LOCALVERSION is probably set to 3.10.0.
If that is the case, try setting CONFIG_LOCALVERSION="" via 'make
menuconfig', and ensure that CONFIG_LOCALVERSION_AUTO is set to 'y'.
Where is this defined?
Can we keep it as the current kernel version or change it as we want?

Alexander,
Thanks for the reminder!
I realized that the new build module is with version "3.10.0" and so not
match with my running kernel version "3.10.0-957.el7.s390x".
I do confirm that i was using the right kernel source rpm.
So, the question turns to why the "make modules" command changed the
kernel version of built modules to "3.10.0" instead of
"3.10.0-957.el7.s390x".
Is there any special steps i need to follow to keep the original kernel
naming convention?
btw: I'm following below article to compile the kernel modules.
https://wiki.centos.org/HowTos/BuildingKernelModules
Thanks!

You mentioned that you were following the instructions to build your
modules using this article,
https://wiki.centos.org/HowTos/BuildingKernelModules.
Which method did you use?
Some of the methods describe setting the kernel version in their
respective config files. E.g. cifs-kmod.spec.
Perhaps your build environment relies on those config files to set the
version of the kernel module?
