[PATCH v2] Append KERNEL_VERSION string to kernel module package names

[PATCH v2] Append KERNEL_VERSION string to kernel module package names

[ola.redell]

From: Ola Redell <ola.redell@retotech.se>

The KERNEL_VERSION string is added to kernel module package names in order to
make the kernel modules for different kernel versions distinct packages instead
of different versions of the same package. With this change, when a new kernel
is installed together with its kernel modules (e.g. by upgrade of the packages
kernel and kernel-modules) using some package manager such as apt-get or rpm,
the kernel modules for the older kernel will not be removed. This enables a
fall back to the older kernel if the new one fails.

Ola, please follow the commit short log guidelines when submitting 
patches. Basically you need to prefix the target where this change is 
applying then a brief description, for example
